Integrated voice and video services for ISDN interfaces

Unanswered Question
Aug 20th, 2008

I'm testing this feature with these scenarios:

7960 + CUVA / 7985 > CCM 5.1.3 > ISR GW 2811 (12.4(20)T) + VIC2-2BRI > ISDN > Polycom ViewStation SP384

7960 + CUVA / 7985 > CCM 5.1.3 > ISR GW 2811 (12.4(20)T) + VIC2-2BRI > ISDN > IPVC GW 3527 (v5.5) > GK > Polycom VSX7000

Both the 2811 and the Polycom has 1 BRI connected. The 3527 has 1 PRI.

The only "successful" call is from the 7960+CUVA vs the Polycom VS, using G.711 A law and H.263. The problem is that I have experience is one-way audio. I don't why we can't connect to the 3527.

Do you have tested it? Can we change opinions?

Thanks and regards!

I have this problem too.

What is the version of CUVA or VTA installed on your Client PC?

Are you using 7961/41 or 7970/71 IP phones connected to these VTA cameras?

What is the firmware version for the phone?

Is this a new install or has this ever worked before?

Do you receive one way video and audio?

Have you checked/tested to see if video works fine?

It's a new installation. I'm using CUVA 2.1, a 7960 IP phone with firmware name P00308000800.

On the Polycom the audio has no delay, but there is a 4 seconds delay with the video stream. The video delay on the CUVA is very low, but there is no audio on the c7960.

Thanks and regards!
