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.

Just to add, When the video call is from Phonr B to Phone A, the video quality is excellent in both scenarios

2 things:
1 "4) Phone A resumes the hold and voilà , the voice quality is now excellent."
did you mean video?
2, the only things that comes to mind is that that somehow you are hitting a bandwith restriction and when you go MoH (that streams locally) you re-initiate the video in the other direction. The two places I would start are the location settings and the region settings. Maybe something is just a little bit off. Another thing would be to check the bandwidth you are using for the streams. If you notice it low before hold and then jump after hold that would make sense from a quality perspective.
