Microsoft Lync Configuration Lync Caller ID Supression

  11:24 AM    Santosh

What if Option #1 won’t work for you? Your gateway guy doesn’t want to do it, your PBX guy doesn’t want to do it, your PBX can’t do it, etc… Well, Lync 2010, again, provides a new option which previously didn’t exist in Office Communications Server 2007 or Office Communications Server 2007 R2.
In order to do to do this, we will need to create 3 new things:
  1. Lync Voice Policy
  2. Lync Phone Usages
  3. Lync Voice Routes
By itself, Phone Usages don’t do anything. They are only the secret sauce that links a Voice Policy to a Route. If we take a look at our Lync Route, we can see the new option for Supressing Caller ID with a specific phone number. In this case, let’s assume +13125556666 is our main office DID.

In the above screenshot, we can also see that we have an Associated PSTN usage record of Non-DID. We also have a Voice Policy assigned called Non-DID users. For our DID users, they will be in a different Voice Policy that utilizes a Voice Route that does not have Supress Caller ID enabled.
If you decide to use this configuration, any non-DID users will have their FROM: field modified to +13125556666 once they are moved into the Non-DID Users Voice Policy. Their SIP Invite message will now look this:
INVITE sip:+18002223333@lyncgateway.internalAD.domain.com;user=phone SIP/2.0
FROM: “Test, Elan”;epid=AA4B5C1773;tag=d57257363e
TO:
So with Option #2, we will end up with the following:
DID Users
  • DID Voice Policy
  • DID Phone Usage assigned to DID Voice Policy
  • DID Phone Usage assigned to DID Voice Route with no Caller ID Suppression linking the DID Users to the DID Voice Routes
Non-DID Users
  • Non-DID Voice Policy
  • Non-DID Phone Usage assigned to the Non-DID Voice Policy
  • Non-DID Phone Usage assigned to the DID Voice Route with Caller ID Suppression linking the Non-DID Users tot he Non-DID Voice Routes
