[cisco-voip] 7965 SCCP 45.9-1-1S and G722

[Jason Aarons (AM)]

CP-7965G to CP-7965G on LAN we have advertise g722  Enterprise parameter enabled. For most all calls it sounds great, however once in a while the end user (always a female) complains it sounds tinny, usually on a phone to phone call.   Workaround is to disable advertise g722.

Is this a known bug, anyone else seen this.  5 different customers over last 6 months have complained about it. All new installs, new phones running 8.5 or higher firmware.

This customer has all 7965 SCCP 45.9-1-1S with G722 enabled and noticed it. Gateway is MGCP and G711, no problems with G711 calls, just G722.

I love G722 and think it sounds great, I can never reproduce the customer's problem but end up disabling advertise g722.
