[cisco-voip] Poor Receiving Audio on 69xx, CUCM 8.5.1

[Anthony Kouloglou]

Hi,
when i say poor audio receiving, i mean choppy (cutting in, in the 
remote site).
This is noticed ONLY on 69xx!!
All 7911, 7961 can hear nice (even in g711) so the upload bandwidth of 
the central site is not the problem.
I didn't want to use g711 since i though it is more bw consuming.
That is why i tried g729 (and ilbc)
All the times, only the 69xx could not receive well (choppy audio, 
cutting in)

BR
Anthony

We recently installed 8.5 and I noticed when the codec was set to "64 kbps (G.722, G.711)" the codec actually used on the call was G.722 and it sounded terrible.  I had to go into CallManager service parameters and set "G.722 Code Enabled" to disabled.  After this, the calls sounded fine.
