If anyone has the time and/or inclination to answer this one, I’d like to understand a little bit more about what’s happening on my Asterisk servers.
I’m seeing an interesting message in the log file when calls are placed on my outbound IAX2 trunk:
The call still goes through and decent quality audio is passed both ways. I’m just wondering what this means at a deeper level and what affect it’s having on the call itself.
My setup is as follows:
ServerA(Asterisk 126.96.36.199) => External facing server connected to VoIP provider (Teliax) via IAX2 using G729 only and internal SIP phones via ulaw only.
ServerB(Asterisk 188.8.131.52) => Internal server connected to all SIP phones using ulaw only.
ServerA and ServerB connected via IAX2 using ulaw only.
The message is appearing in the message log on ServerA
ServerA and ServerB are in two physically separate locations connected by a 50Mb/s microwave link.
An external outbound call would then look like:
EXTEN[XX] =>SIP(ulaw)=> ServerB =>IAX2(ulaw)=> ServerA =>IAX2(G729)=> Teliax
Am I still maintaining G729 compression on my IAX2 channel to Teliax?
Thanks for any insight you can provide,
