Hi Joe & Jeff,
I got the Lync calls to work, so now it can call either from Cisco phone to Lync client, and Lync client to Cisco phone.
One thing though, the speed of the call setup is very poor, despite the CPU of both the Lync server and the CallManager are very low. Both the CPU of Lync Server and the publisher are running around 10% CPU all the time. But it can take between 7 to 10 seconds after I press the 'Dial' before the other side would start ringing. The same goes when I 'hang up' the call on one side, it takes 7 to 10 seconds for the call to be disconnected on the other side.
From the Publisher, I ping the Lync Server under OSAdmin and it is always 1ms. I also tried to ping both Publisher and the Lync Server from the tested Lync Client PC, it is always 1ms to both servers too.
Would appreciated your help. Cheers,
