Lync 2013 – Configure Voicemail Escape

Hello All

Tuesday’s 1 a day lunchtime blog post for this week

For todays lunchtime blog posting, we are going to look at setting up and configuring Voicemail Escape.

What’s voicemail escape.??? well this is when you have simultaneous ringing set on your Lync 2013 with calls routing to both the Lync client and also to your Mobile/Cell via PSTN.

Why do I need voicemail escape.??? The gotcha and need is if your Mobile/cell is out of range OR busy OR turned off OR out of juice the call will get picked up straight away by the voicemail on the mobile/cell. What the voicemail escape does is it allows for this and ignores the mobile/cell trying to pick the call up instantly and sending it the the Mobile VM.

Adding the required powershell command will mean that if your mobile/cell is off etc, the call will continue to ring on your Lync client then it will route to the LYNC Voicemail as part of the Lync installation.

Using the Lync powershell command we need to add further config information to the Lync voice policies as part of the Lync installation.

Start the Lync Server Management Shell: <thanks to MS for the copy/Paste below>

Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

  • Specify the following parameters to Set-CsVoicePolicy:
    • EnableVoicemailEscapeTimer – Enables or disables the escape timer.
    • PSTNVoicemailEscapeTimer – Specifies the timeout value in milliseconds. The default value is 1500 milliseconds, and the value can range from 0 milliseconds to 8000 milliseconds.

<2000 milliseconds = 2 seconds>

Example of the powershell Command

Set-CsVoicePolicy <UserVoicePolicy> -EnableVoiceMailEscapeTimer $true – PSTNVoicemailEscapeTimer 2000

NOTE: its worth testing the milliseconds from smallest to higher number ie: 2000ms > 2500ms > 3000ms

escape

once this is done, you can still in the powershell type Get-CSVoicePolicy ~ fl which will give you all the information/settings for the voice policies in Lync

That’s it for this blog posting. For your understanding now. Any calls to a user who has sim ringing enabled to their mobile/cell and to which there mobile/cell is turned off, the call will continue to ring and ignore the mobile/cell VM trying to pick up the call.

***Added note: you can take it a step further and add custom on-hold music etc as part of the voice policy etc. For information on this follow the TechNet article on configuring voice policies. http://technet.microsoft.com/en-us/library/gg398511.aspx

    • Thank you for your none constructive comment. Funny enough you’ve actually read my blog to point out the error, so your comment isn’t that true now is it. Also i feel the need to point out i have over 300,000 hits per year so someone is reading it, or maybe thats just you sat in your two up two down house in Lancaster pressing f5/refresh. Either way thanks.! troll.

  1. Great article thanks Ian – it came back in a google search to my issue and its helped me out so ignore the troll!!! one issue we do still have though is that I’ve added the setting to a max of 8 seconds but still have an issue for a user who has sim ring setup with their mobile where no Voicemail has been setup. it will ring the Lync client but after the 8 seconds the caller will get the “it has not been possible to connect your call” even though the Lync client calls…. any ideas??
