How does CAC work on Audio Video Confernece (AVMCU)?  If a site has limits does AVMCU follow CAC Rules for that site?   I start testing the Lync 2010 CAC features on two sites and I have setup them up as follow:

Testing1:  Disabling Audio Video on sites.

Audio Limit: 0
Audio Session Limit: 64
Video Limit: 0
Video Session Limit: 512

My test plan is to start disabling Audio and Video feature and slowly increasing limits, since I only have 2 sites (3 endpoint on ea) and see if the CAC Rules works.

1. I test Audio\Video from site to site and as expected is BLOCK since the limit is 0 for Audio and Video.  This work correctly!!!
2. I test Audio\Video between end points in same site and it was ALLOW since CAC does not apply in this case.
3. I test Audio\Video to connect to a AV Conference and the user was ALLOW - ** Here where I have a problem shouldN'T the CAC apply and BLOCK the end user to connect to the AV Conference since the limit is setup to 0 audio and 0 video?   <----- Can someone help me on this third scenario testing????

When the Lync client connect to the AV Conference, who check for CAC policies, the Lync client or the AVMCU Service?  Who is in this case the receiving endpoint?

Also, another question:  Does CAC apply if users are configured for PC-TO-PC Only?  In the above scenarios user are setup to Enterprise Voice, but I'm currious if CAC also works for user setup as PC-to-PC only as Telephony.

Hope someone can help me.  Thanks for your input.

Thanks, PR

Hi,PRJUANL,

In your third scenario,are these three users in different location?If they are connect to Lync server in the same location,even IF they are homed on different site,the CAC policy will not work since CAC policies are enforced according to where the endpoint is located, not where the user is homed.

If they are in different locations to connect to Lync server,plese check if they are other routes to resoute the call,for calls that fail because of CAC policies, the order of precedence for rerouting the call is as follows: Internet,PSTN,Voice mail. You also can enable Lync server logging to trace the log to get more inspection on how CAC works.

Yes,CAC also apply to PC-TO-PC only as long as it's a voice call or video calls or audio/video conferencing sessions and the users are in different network sites.

All,

I found the issue, I had the wrong Subnet ID and Mask bit for one of the sites I was testing on.  Once I corrected this, the Lync clients were BLOCK to join the AV Conference.  Also once this was fixed, the Lync clients were BLOCK to join the Polycom Endpoint HDX 9000 and 4000.  All good so far.

Great Testing!!!
