Strange behaviour video call.

Hi all,

We are facing a very strange issue with one of our customers.

We are using CUCM 8.6 , 9971 phones and cisco Cius.

The first scenario is as follow:

1) Phone A (9971, HQ, DP-HQ, REG-HQ) places a video call to phone B (9971, remote site , DP-Site B...)

2) Phone B can see user A with a good video quality but the quality is poor at the users A phone.

3) Phone A puts phone B on hold, phone B hears MoH (Multicast from flash).

4) Phone A resumes the hold and voilà , the voice quality is now excellent.

The second scenario is as follow:

1) Phone A (Cisco Cius, HQ, DP-HQ, REG-HQ) places a video call to phone B (9971, remote site , DP-Site B...)

2) Phone B can see user A with a good video quality but  user A connot see at all user B (Black screen)

3) Phone A puts phone B on hold, phone B hears MoH (Multicast from flash).

4) Phone A resumes the hold and voilà , the voice quality is now excellent.

Any help is much appreciated.

Regards
