I am using the following setup:

The system works great for the most part. Most people I call say it
sounds good. However, every time I call a certain company that uses a
ShoreTel system, they claim the sound is garbled (understandable, but
not pleasant to listen to). Everything sounds fine at my end. If I
make a call w/ the following setup, it sounds fine:
Analog phone -> Asterisk:TDM400 -> NuFone -> PSTN -> ShoreTel system
So, it seems there is some type of weird interaction between my system
and the ShoreTel system if I use the SPA941 IP phone.
Does anyone have suggestions as to how I can start debugging this?
Check the RTP Packet Size (under the Sip tab). Set it to .020 (20
milliseconds) and place another test call. For whatever reason, the
Linksys/Sipura products default to 30 milliseconds and has impacted the
quality of audio on some systems.
