Recently i have seen the issue of your public cert missing its key on import. The situation is when you create the required .req for your public certificate on edge you send the details off to the certificate authority of choice. Once they create and return the .crt file and the necessary trusted root and intermediate certs you import them into the Lync edge server only to find that the ‘sip.<domainname>.com’ cert is missing its private key.?
Why would this be the case when you originally generated the request on the Lync edge server? At this moment the only reason i can see is if another certificate with the same name has previously been imported onto the server. Apart from them i cannot find any other logical reason for why sometimes the newly imported certificate misses the private key.
if you are in this position, the simple fix to the cert is as follows
– On the imported certificate without the private key, double click the cert to show the information associated with it. Click on the details tab and look for the field called ‘Serial’. Copy the serial key into notepad and remove the spaces below the unique code. ie
WAS 5a 12 6e 7e ee 11 AMENDED 5a126e7e11
now still on the edge server open command prompt and type the following
certutil –repairstore my <Amended unique serial number>
eg: certutil –repairstore my 5a12637e11
press enter to commit it.
you will then be presented to information and also confirmation that the update has been successful.
now if you go into the certificate store and refresh you will see the certificate will now have the private key within it.
At this point you can go back to your Lync deployment wizard and assign the public cert to your edge server.
I haven’t seen much around guides on how to create custom reports for Lync 2013 so i thought it would be good to share the mechanisms on how to do this with the native Monitoring reporting tool which can be co-located with the Lync 2013 frontend.
For this guide I’m running a Lync 2013 Frontend patched upto CU version January 2014, and SQL Server 2012r2.. All servers are running windows 2012r2 and patched unto date.
Step 1.
Ensure the current reports are working as expected
Next step is to go to the SQL Server you provisioned and open up internet explorer and navigate to the reports path/URL for this demo that would be
Also if you are unsure you can find the path required by going into the SQL Reporting Services configuration Manager and selecting reporting Manager (as below)
ok now we have navigated to our browser page lets select the report builder option.
NOTE: Depending on your original setup up, you might have to download and install the actual report builder application. (you will be prompted for this download if you haven’t already got it installed.)
Once installed or when the new dialog appears – Now select ‘new report’ as this is what we are wanting to do.
Once you’ve selected the table wizard, accept the default dataset ‘create a dataset’ and click next.
Now you will be promoted for a data source, for Lync we need to browse to the data source down the tree.
select it and click ok. then do a quick test connection for clarity. now select Next, and when prompted add the credentials of your ‘privileged’ user account
Once you’ve added this information, you will be presented with a dialog which is called design a query. In this you can create your own report based on the information held within the Monitoring database. (everything), NOTE: it would be worth getting hold of the Lync 2013 database schema to understand all the tables available to interrogate.
for this demo, I’m going to select a stored procedure calls GetSCOMAlertData. this store procedure in the report and information which is passed to the SCOM application for reporting. in this scenario you don’t need SCOM, but you can get reports on what information would have been passed. I find this useful for monitoring your Lync environment. Also you could if you already had a reporting tool ie: Crystal Reports data mine your own information onto a crystal report and interact with other internal system databases.
On the arrange fields page drag and drop the required fields into the rows and columns
on the next couple of pages select your layout and style and select next/finish
once this is complete you can select the ‘Run Report’ button to see your finished result. If your not happy you can go back and redesign the report as you wish.
Once you’ve tweaked your report to suit, no select save and navigate to the lyncserverreports folder and give your report a name and select save
now if you go back to your browser and select the original reporting path, you will see your newly created report within to select
Thats it.
As i say there is a whole raft of information available to report on, so before you start i would suggest you have the report requirements at had and also have a good understanding of where within the CDR database that information is stored.
Its been a couple of weeks since my last video guide. On request from other people within the UC community it was requested that i complete a installation guide around Sonus’s SBC Media Gateway appliance.
In this video guide details information on how to configure the gateway with a SIP trunk. (courtesy of PureIP). http://www.pure-ip.com and also connection with T1 and E1 trunks.
NOTE: For those people who are interested in the T1/E1 element only this start 54 minutes
Please leave any comments of feedback as well as further guides which you might like to see.
This blog post and video guide describes how to force the Lync 2013 client to always show the end users Lync picture even after the user might have changed the setting not to show the picture.
To but a little bit of background around this, as with Lync 2010, Lync 2013 does not have the ability to block or stop a user from deselecting the option of showing their Lync picture. This picture element is something I’m asked many times while working with customers.
I know this is something which we all would like as a option but as of today and as far as I’m aware this isn’t something close to Microsoft’s heart in fixing or providing a solution.
Also to confirm there isn’t any policies you can assign OR and registry setting to can associate to block the user changing their setting. So what solution and where is this setting stored….. Well its not in the xds database and actually its started within the front ends rtclocal database.
So to confirm before you go any further in the blog, I’m pretty certain that this solution will be one thats unsupported from Microsoft and also one that as we are going to change the rtclocal will be seen as a ‘borderline’ hack. Also i would like to point out I’ve ran this within my lab without issue for sometime, however i would suggest you test it within your lab area before you embark on using it in your production environment. <remember I hold no responsibility> 🙂
Ok no the small print is out of the way, what is the fix.. ?? Within the rtclocal there is a table called publishedstaticinstance which has a field that holds a massive binary value. As part of the challenge is to convert the binary into something thats readable and something we can update
Under the covers what this binary code states is DisplayADPhoto true/false.
So as part of the update we change for the status and update accordingly when the status is false.
As this is running on rtclocal, the way the guide runs this is via a scheduled task running a .ps1 powershell command. Also the SQL only checks the last 15 minutes of changes to reduce locks and database processing. Also the scheduled task I’ve created runs every 15 minutes so with the two you will never be out of sync with what a user is doing. (you could run this script more regular than every 15 minutes but given the requirement i think 15 is a good medium to use).
As for the SQL command some thanks go out to the tech net community as understanding the converts within the SQL was a slight challenge.
PS1. Script
function Enable-UserPhotos ($Domain, $OffSet) {(Get-CsPool (Get-CsComputer “$(hostname).$Domain”).Pool).Computers | % {Invoke-Sqlcmd -Query “update rtc.dbo.PublishedStaticInstance Set Data = CONVERT(image,convert(varbinary(4000),REPLACE(convert(varchar(4000),convert(varbinary(4000),Data)),'<displayADPhoto>false</displayADPhoto>’,'<displayADPhoto>true</displayADPhoto>’))) where [LastPubTime] >= DATEADD(mi,-$($OffSet),getdate()) AND convert(varchar(4000),convert(varbinary(4000),Data)) like ‘%<displayADPhoto>false</displayADPhoto>%’;” -ServerInstance “$($_)\RTCLOCAL”}
} Enable-UserPhotos -Domain ‘your domain name here’ -OffSet 15
KEY TAKEAWAYS
Remember the script is changing the rtclocal database on the fronted and this will be seen as not supported by microsoft.!
This blog post details how you would go about adding a trusted application to your Lync 2013 topology.
For this example I’m going to add the trusted application built by Johan Veldhuis which allows for configuration of the SefaUtil commands at a GUI level.
For the people who are unaware of what the Sefautil is. This is the extension features which is part of the Lync 2013 resource kit which allows for remote configuration of users call forwarding, sim ringing and call pickup group option. So essentially you can administer a users settings without whiteout actually visiting the users desk.
Johan has created a great utility which is GUI based as apposed to the powershell commands which is default to the sefautil running.
You can find details on Johan GUI here. http://johanveldhuis.nl/en/sefautil-gui/
ok back to the trusted application piece. Creating a trusted application is the same process contrary to what the software application is which you are wanting to use.
Starting the trust..
STEP 1
Creating the new trusted application pool. For this we do need to initially run some powershell commands to get us going, but before we do that we need to find some information about our pool to add to the powershell command. to do this we need to run the following PS Command
Note: you will be prompted at both PS commands to run the enable-cstopolgy command. its at this point now you need to run it
Enable-CsTopology
STEP 2
We are now complete with the Lync management shell and the powershell commands for setting up a trusted application. (its also worth noting if you went into your Lync control panel or the Lync topology the application trust will now be showing within these areas)
go ahead and install it using the default locations etc. <default location \Program Files\Microsoft Lync Server 2013\Reskit.>
STEP 3
Now lets check that our commands do actually work from a cmd line approach. To do this we need to open up the normal command prompt but as Administrator and navigate to the default location path of the sefautil. (ABOVE Path).
Once you are within the Reskit folder run this command line
Running this will bring back the current call settings for the user.
STEP 4
Now the final piece of running Johan’s SefaUtil GUI.
to do this we need to head back to the Lync Management shell as Administrator and select Johan’s Powershell script. To do this navigate to the script (NOTE: you need to unzip the .zip file first)
Once your with the folder where the .ps1 file is located run the following command
<You will/might be prompt for a execution policy issue before the .ps1 will run.> If you are type this command set-executionpolicy Unrestricted. Then run the .ps1 command again.
Once the GUI is open you will have the ability to administer your users call settings.
Thank you for looking and below is the videoCast of me doing the above in my lab.
AND massive thanks from the Lync Comminitity goes to Johan for the excellent SefaUtil GUI.! You can find more information about Johan and the things he’s working on at his blog site. http://johanveldhuis.nl/
Following the news from Ferrari that the new Virtual SBC OfficeMaster Gateway was available as a trial, i thought i would take the opportunity of deploying and configuring the gateway with connection to my SIP trunk via Provider PureIP.
Instead of the normal line by line installation guide, this time around I’ve completed a video guide of the actual installation and also the call testing.
The video was recorded using software, cam studio and the audio was captured using a Plantronic Blackwire 710 headset
Key takeaways for me was the gateway is different to other vendor gateways whereas with the Ferrari appliance you complete the configuration via a GUI rather than a webpage portal to the appliance. The configuration was straight forward and nothing to taxing. One thing of interest to me was the gateway can work in a single NIC mode or in dual NIC mode for hand off between NICs. (Similar to how an Lync Edge server hands over from the internal NIC to the External NIC).
Also i think there is a wording issue on the tabs while setting up the routing as one tab says ‘Calls from ISDN’ when in fact it should say ‘Calls to ISDN’.
All in all, i was really pleased with the setup and installation of the gateway, and i look forward to getting my hands on the new physical appliance being released in Q1 2014.
Following a months worth of bench marking tests of the three main vendor high-end wired headsets available to Lync (optimised devices). Below are the details on the devices and information around the benchmarking criteria plus my unbiased opinion.
With what is now tradition, i will be using the same metrics/categories as i have done in the past with other Lync headset/devices reviews completed. I will score each headset on the following metrics, plus also giving an unbiased synopsis including RRP pricing guide.
The four categories are (Sound, Functionality, Usability, Cost) AND a new Category
Sound quality of Music playing– this is something new I’ve added to the reviews and i would say it isn’t something i would use as the main driver for buying or not buying a headset on. The reason for adding this is on my other blog posting at NorthernLync in the past, i have had people asking me about using a Lync headset to listen to music between calls. Personally i don’t think any optimised Lync headsets were manufactured to be a dedicated music playing device, but as I’ve been asked the question I’ve added it into the review anyway.
From Left to right are the ‘flagship’ headsets from each vendor. (Jabra BIZ2400, Plantronics Blackwire 720 and Sennheiser SC630) ***All the headsets i was testing were in mono ear’d format. (my preference)
First up the Jabra Biz 2400
Sound – It has to be said from the start of this review, all the headsets had the sound quality marked as excellent. For the Jabra i found the inward sound to be crystal clear on Lync calls. Also i had comments about the clarity of the outward sound. On a few occasions the recipient of the call did ask if i was the only person working in the office as they couldn’t hear any background noise whatsoever. Also on the odd occasion where i was not talking i had the end recipient saying ‘hello’ back at me as the headset almost felt like to them it had put the call on mute and as described by one caller as ‘pure silence’. That said i was impressed with the sound quality for day to day Lync calls.
Sound quality via Music playing – I found it a odd experience and maybe this was due to listening into one ear only, but I think the music lacked bass, and high pitch tones on some songs played. Also it was a little bit ‘tinny’.
Functionality – As well as good call quality sound, the BIZ 2400 comes armed with a ‘puk’ sized device attached to the cable. On standard day to day use this is were you would alter the volume and mute/answer calls. The wheel function in the middle endlessly turns and a in-ear clicking noise on rotation is heard. One the secret weapons the BIZ 2400 does have in its armour is within the same Puk device that holds a bluetooth receiver which allows you to pair with your mobile phone and allow for using your headset to make and take mobile phone calls. neat eh!! well hold on a second… it is a neat feature until you close your lid of your laptop, or turn / lock your desktop.!! at this point the bluetooth dongle in the PUK looses the power and without a inbuilt battery it stops working.!! Also i should note the boom arm also rotates a full 360* which i guess is a feature but not something i would play on as part of promoting the product.?
Usability – I used this headset for a week in the testing phase, and i can say i never thought anything untoward about it.. its a nice piece of kit. it was comfy to wear for long periods, sound quality was good. The nice leather ear pads felt like cushions against your ear. Also within the box came a kind of nylon bag to keep your headset safe if you was in the need to remove it each working shift for storage
Unbiased Verdict – I was moderately impressed with the BIZ2400, and would recommend it to customers who were biased towards Jabra and who was in the market for a high end device. ALSO Jabra tells me there are 20 different types of this headset to suit different scenarios, so if your in need of a custom/different headset requirement its worth looking on their website.
RRP – £129 is the market rate on these at this moment which sits in the middle pricing of the three devices

Next up the Plantronics Blackwire 7xx Series
Sound – The sound quality with the Blackwire 720 is excellent as you would expect with any premium high end device. There are some really nice additions to the features for sound on this device which makes it a more preferred headset over the Jabra. See below.
Sound quality via Music playing – Now if you want a headset for Music playing, then this and the Sennheiser below are the ones to choose. The Blackwire boasts stereo sound which came across as a really full crisp sound on playing a variety of music types. (sorry I didn’t try it on heavy metal), but for ‘day to day’ music it sounded great even through the single ear.! AND a feature which i thought was brilliant was the fact that when you was playing music and for whatever reason you took off the headset, it would pause the music automatically.
Functionality – As well as the really good call quality, the Blackwire series is packed with gadgetry which is the leader in its field. Below is some of the neat gag which is inbuilt into the headset
On pickup of the headset when a call is ringing in your Lync client, the headset automatically answers the call;
Same bluetooth style connection built into the headset but this headset also comes within a inbuilt battery meaning you can unplug it from the desktop/laptop and the headset still work over bluetooth;
If on a bluetooth mobile call, then the device is clever enough to put your Lync status as in a call.;
The ability to move a call from your mobile to Lync via the headset without having to redial;
Headset battery status visible from the toolbar of your desktop/laptop, so you know how much change you have to play with on bluetooth only calls;
If there was a very small negative to take from all the great functionality is that the bluetooth range isn’t particularly vast. I can only get to 3 metres from the mobile phone before the sound became choppy.
Usability – I love it, i would be happy to use this headset day in day out, both for calls in quiet and noisy places. It also comes with a formed padded carry case to provide a good level of protection.
Unbiased Verdict – I can’t state enough i think this is one of the best wired headsets I’ve ever used with Lync. The features are top notch, the sound is excellent for calls and music. This headset without doubt will be going into my kit back for client recommendations.
RRP – less than £100 at this moment, which makes it £30 cheaper than the Jabra BIZ2400. In my opinion i would be going for the blackwire over the BIZ2400 even if the pricing was the same. For me Its a no brainer going for c720 over the BIZ2400.

Last up is the new kid on the block, the Sennheiser ‘Century’ SC630
Sound – What can i say, by default the sound quality of all the Sennheiser devices spreads though there product range. The SC630 isn’t an exception to this as the audio quality is high-end. Sennheiser states that the Audio is HD audio which i do agree with.
Sound quality via Music playing – As with the the Plantronics Blackwire device, the Sennheiser headset also sports the concept of allowing for high quality stereo music. this it does really well, and i would say it is a better sound on music playback over the Plantronics. This music sounds rich and clear.
Functionality – As well as the excellent call quality of the sound for calling and Music, the Sennheisers SC630 build quality is to a high degree using premium end materials. The look and feel of the headset ouzes premium grade quality. Although the functionality isn’t on the same level it terms of gadgetry, Sennheiser has chosen to go down the build and quality road to give the end user the best sound and device quality experience. Below are some of the features detailed from Sennheiser on the SC6xx devices.
Sennheiser HD voice clarity – wideband sound for a natural listening experience
Ultra noise canceling microphone for perfect speech transmission
Sound-enhancement profiles – perfect for communication and music
High-quality neodymium speaker for outstanding HD audio quality
ActiveGard® technology protects users from acoustic shock and sudden sound surges
Call control unit allows for easy answer/ end a call, volume up/ down, microphone mute and redial last outgoing call
3 years international warranty
Unbiased Verdict – If you want a excellent sounding audio headset which is as good running Lync calls as music playing, plus with a excellent build quality then the SC630 is the one of choice.
RRP – As this device is relatively new to the Lync market, the price point is the highest of the three devices at £149 per headset. That said, that old saying goes… you get what you pay for and with the SC630 its high-end quality throughout.

Overall Verdict and Star Ratings.
I enjoyed using all the devices i tested and reviewed, they all did what i expected them to do. Also it was refreshing that i didn’t have to write any negatives about the devices. If i had to choose a winner and a preferred device of choice, based on build quality and sound preferences i would suggest the Sennheiser SC630. If you was wanting more technical features along with excellent sound quality to match then the Plantronics c720. Sadly i think out of the three headsets the BIZ2400 just didn’t cut the mustard in both in build quality or technical options.
Jabra BIZ2400
Plantronics c720
Sennheiser Sc630
***Also to note, all of the headsets were tested with Office for Mac Lync as well, and all preformed as expected.
Thanks for reading. the next device review will be around the mini conference devices.

The below is a unbiased view on three dect headsets that are all certified and compatible with lync 2013 and Lync 2010.
Using the same metrics/categories as i did with the bluetooth device review, i will score each headset on the following metrics, plus also giving a Pros and Cons synopsis including RRP pricing guide.
The three categories are (Sound, Functionality, Usability)
(Left to right, Sennheiser DW office, Logitech h820e, Jabra 9470pro)
Dect Headset No1
Sennheiser DW Office
Sound – There is one thing to say with all the Sennhieser devices I’ve used and reviewed ALL have the best sound quality across the UC field. Again like the Sennsheiser bluetooth Presence device the sound quality is crystal clear. I’ve been using a DW office now for many months, and as the other two dect headsets have been released i’ve used these other devices for weeks at a time but it must be said its never ever been in my mind to replace the DW office. Simply put, its head and shoulders above the Logitech dect headset for sound. I’ve used this dect device in my daily job accepting calls from SIP connections/PSTN and Mobile and the device has never missed a beat.
Functionality – As with all three headsets they all almost mirror each other with basic functionality with some having nice little extras over the other. For me the Sennheiser has a couple of neat features. One – being that it does not need a power supply to feed it an electric current. Its happy to utilise the USB connection to the headset to power it. (its worth noting this is the only dect headset in the review which can do this). Two – thedevice can also twin and connect to a desk-phone for better together capabilities. Three – you can twin unto 4 headsets to one base station. (this works well for training purposes etc), Four – it can be connected to your mobile/cell phone as well as a Lync headset.
Personally a trick the Sennheiser doesn’t have which would in my opinion would have been the icing on the cake is the lack of ringer in the base unit. More and more companies are not buying new desktop machines with sound cards and speakers these days as they are doing this to cut down on the revenue costs on hardware.If the DW office had the ringer function this would be perfect. I would hate to think one of my clients dismissed this excellent device due to a lack of ringing from the base unit. (note: only the Jabra dect device has a ringer in the base unit, but sadly that lacks in other areas)
Usability – I can sit with the headset on for hours and even sometimes i forget im wearing it until I’m reminded :). there is comfort and quality all around this headset. On first opening of the box, you might find the boom arm is very close to your cheek, this is by design and within the box is what Sennheiser calls a cheek deflector which is a little piece of plastic which snaps onto the start of the boom arm and makes the arm move away from your face area. The ear peice is leather and very comfortable to wear.
For the distance on how far the dect range is (Line of sight 134mtrs, within a office <none line of site> 46mtrs)
Unbiased Verdict – the quality is what you would expect from Sennheiser devices. excellent sound and build. I wish it had a ringer in the base until as this would be in my opinion be the perfect all round product. Price point of this dect headset is the most expensive and could be seen as to expensive by some.
Sound – When i first saw this headset at the UC Expo in London in March, i couldn’t wait to get one of these devices to test and ultimately use in my day to day job. Oh how disappointed i was with this device when i received it. The sound is just awful, the boom arm and mic is super sensitive to the point where you can’t stop the sensitivity. (this is the same with the USB wired version). You literally have to move the flexible boom arm to a right angle to stop the sound distortion. Even with turning the sound down to the minimum setting within Lync makes no difference.
Functionality – Barring the sound issue, functionally the headset has a unique feature of showing the incall presence at the backend of the boom arm, this in itself is a nice feature when the headset is in use, people can see your on a call. As with the Sennheiser device, this dect device also doesn’t have a ringer option within the base unit. When the headset isnt being used you dock the headset vertically back onto the base unit, and there has been a few times where i thought it was docked but due to it being placed into the dock misaligned, it never charged and wasnt good enough to use on my next call.
Usability – The headset is really comfy with nice leather big ear pads and leather headband. Logitech have really thought about the comfort of this headset and it is as good if not better than the Sennheiser and Jabra devices . For the distance on how far the dect range is (Line of sight 64mtrs, within a office <none line of site> 31mtrs)
Unbiased Verdict – I can imagine the Logitech guys sitting round a meeting room table and saying ‘we have X amount of budget how do we use it…’, i think they spent 85% on comfort, and the remaining on the actual base unit, headset and packaging. If there was one saving grace for the logitech device its the price, its unbelievably cheap for a dect headset. You wont find a cheaper dect headset on the market. Downside is the sound, its a massive issue with this headsets.. Sort the mic sensitivity Logitech!! fix this and you will have a great UC device at a very good price.
Sound – The sound from this headset is really good, nothing really to complain about. On using it i hear no white noise and distortion, and the difference between the Pro 9470 and the Sennheiser DW office is the DW’s sound is more digital and clear. That said if id bought the Pro 9470 i would be happy to use it day to day.
Functionality – In terms of design of both the base unit and headset are both nice. i like the base unit lcd touch display which enables you to flip connections from desktop to bluetooth/mobile phone. ALSO it has the ringer which i really like and one i see customers asking more and more for. As for the headset it fits nice with large leather ear pads, and it also feels light on your head.
Usability – I used the Pro 9470 device of choice before i received the DW office. If the sound was just a little bit clearer i would be hard pressed to choose between these devices. I cant emphasise enough about the ringer feature and how useful it is.
Unbiased Verdict – This is a really good bit of kit, and one i would recommend to a client. There is nothing i can fault.
This is a relativity simple verdict, and if you see this as gold, silver and bronze awards. In third place is the logitech h820e this is because of its poor sound offering. In a joint first place is the Jabra Pro 9470 and the Sennheiser DW office. Reason why i cant make a distinction between these devices is due to the following. For the Jabra Pro, i cant fault the device in anyway, i like the base ringer option, and the base lcd touch display. Plus the device is £100 cheaper than the sennheiser DW office. For the Sennheiser DW Office I can’t get away from the quality sound and hardware. Also with the ability to add additional headsets to the base units, its perfect for training purposes. Downside for me is the price, you have to have deep pockets to afford a few of these if you are a customer.
– If you are a person who wants the best sound quality then in my opinion the Sennheiser DW Office is the best
– If you are a person on a limited budget and aren’t bothered by having the boom arm at a right angle. The Logitech is a good match
– If you are a person who wants a comfort fit with good sound quality and a long range of connectivity then the Jabra Pro 9470 is the one
Wednesday’s 1 a day lunchtime blog post for this week
For this blog post its fairly straight forward, but I thought I would document it as the TechNet article I think doesn’t give you the full picture on what the config should be.
We will do a 80/20 split of the config with the main part of the setup being completed in the Lync Control panel and the remaining 20% part being completed in the Lync Management Shell.
Without further a do. lets start..
open up the Lync control panel and navigate to the Voice Routing selection on the left, then select the VoicePolicy area on the top panel.
Now Select your Voice Policy
Now select to enable call park, then select OK and then Commit your change
now select Voice Features from the left hand pane, then select call park from the top option
Now we will add the telephone number range,
select new, then give your call park a name, add the number range and also the pool to which associate the call park with. Now select OK
last thing we need to do is amend our dial plan as reteriving a parked call will ring between 1000 and 1005 WITHOUT a + at the start and therefore it will fail to connect. So what we need to do is add another dial plan rule to cater for the call park numbers.
Goto Voice Routing, select Dial Plan, then your dial plan. Now click new on the associated normalization rule.]
let now add the new rule for the call park numbers
DONT forget to test your rule and also move it up to the right order within the rule base.
thats it. set up. You can take the Call park a little bit further by running the powershell command Get-CSCpsConfiguration, instead of the Get you can do Set and change the amount of attempts to pickup the call, the amount of time the call will hold for before reverting back to the callee and also to allow music on hold. (if you wanted custom music on hold you would need to amend the CsClientPolicy path for music on hold)
