We have our SIP trunk set to PCMA codec, our phones are also set to PCMA codec and we have checked this is all correct.
The extensions have the option "PBX Delivers audio".
Most of our calls received are in PCMU, is there a way to change this so when teh PBX generates or translates audio, it uses PCMA?
All this trnaslation is a waste of CPU time and a reduction in quality. This issue has been identified since I went to G722 (wideband) and people complained that the sound was unnatural, this seems to be because we are stuck with PCMA on the SIP trunk so there is a translation from GCMU to G722 which makes the sound unnatural.
Thanks
