3CX GSM Codec and Cisco CME Unified do not work

[campestrindanilo]

Hello to all!!

I set up successfully a 3CXPhone on a mobile phone running Android.
The 3CXPhone works great with my Cisco Router with installed CIsco CME Unified Communication using as codec
the G711uLaw or the G711aLaw.
Instead there is no way to get correttly running the phone using the GSM protocol (g729)
I set up on the Cisco the g729r8 bytes 40 (that should be the standard config)
The 3CX registers correctly but is then impossible to make a call.

Any idea?
