I have an issue working with the connection between certain Cisco IP phones 7940 and 7960 which works with firmware version cmterm-7940-7960-sccp.8-1-2.cop.sgn.
The problem is that when I connect my PC in data vlan and the phone using the phone PC connection the CAST protocol is not constantly connecting at the CUVA application. The CUVA version is 18.104.22.168.
If I test using the same switch port and the same PC but another video enabled phone. then the connection is stablished properly and consistently.
I can send you the CUVA problem report in one of the cases If you needed.
Thanks in advance,
