We are using CUVA 2.1.1 with 7961 phones.
The phones are running firmware ver SCCP41.8-3-3SR2S.
Calls are being made between two phones at the same location, in the same building, on the same vlan.
Sometimes the initial video call will work but then a second call will fail.
Sometimes the initial video call won't work though.
It seems the CUVA software doesn't discover the IP phone even though CDP protocol is running.
Here's what is happening:
â¢ When the CUVA software is started, it will sometimes see the IP phone. As soon as you make a call the connection to the IP phone drops. (Unified Video Advantage is not connected to any phone error). A yellow triangle with exclamation point appears over the CUVA systray icon.
â¢ Starting CUVA after the call is made is the same. IP phone picture is grayed out (Cisco IP phone not present error). A yellow triangle with an exclamation point appears over the CUVA systray icon.
â¢ Letting CUVA sit open in hopes that it eventually associates itself with the phone doesn't always work. Maybe one of the two CUVA will recognize the phone but no video will work on the call.
Tried increasing camera video bitrate...it did not fix the problem.
Increased bandwidth at the location in CCM...it did not fix the problem.
Pulled the cable to physically reset the phone, and reset the phone device in CCM, and reboot the pc...this did not fix the problem.
Ran the diagnostic detail log on CUVA but it captured nothing when the problem is happening (Cisco IP phone not present error). It logged only when video conference is working. When the CUVA connection to phone drops no error on screen except the Remote Video Windows going dark and closing and the log stops capturing data.
Any ideas or suggestions would be greatly appreciated!
