Hello all,
we made an update to
Cisco Unified CM Administration System version: 6.1.5.10000-10 and after about 2 weeks, we have an issue with the ata 168 only in the Headquarter.
We can call from and to the ata's, from inside and outside , but the most time the voice quality is very very poor and its sounds like a robot with many breaks.
Any other phones 7911, 7970, 7971 are ok.
Here is an sample of the ata device information and network conf:
