CAC policy not working RRS feed

  • General discussion

  • I have the following Lync server 2010 installation configuration in my software firm.

    Lync server standard Edition.

    lyncfe.neyeball.com (Local Front end Lync server collocated with mediation server)

    lyncdc.neyeball.com (Domain Controller and DNS server)

    lyncedge.neyeball.com (Edge server)




    I want to implement CAC policy in this installation. For this, I have shut down the Edge server.

    I have one subnet of I have devided this into two block. and and place two Lync client in these two subnet with ip and Then I configured the Lync server with two sites having these subnet.

    Site1 -->


    Then I made a BW policy profile and applied the BW policy in both sites. Media bypass is disabled.

    The policy profile was like following:

    Audio limit: 0

    Audio Session Limit:40 (this is the minimum)

    Video limit: 0

    Video Session Limit: 100( minimum)

    I also executed the command "



    Then I tried to make call between the two Lync client1 and Client2  which subsides in Site1 and Site2 respectively. I hoped that call would not establish. But the call established perfectly. That means CAC policy was not applying.

    Can anyone tell me why the CAC policy was not applied or I would be greatful if anyone can tell me what I need to do to enforce CAC policy in a single Lync server installation.

  • Hi ,

    Can you clarify following ?

    1. Are these client machines are connected to same VLAN ? Is call established via peer-peer connection ?
    2. Enable UCCP logging and check in-band provisioning message , It should haveCAC policy information ?

  • Hi,

    check also that the two PDP Services are installed on your Lync Server and running. If you have deployed a Monitoring Server, you could also look for the CAC reports.

    Why have you shut down edge? Is it still defined in the topology?
