[Asterisk-Users] enabling G.729 for SIP

[Jim Gottlieb]

We have bought and installed 10 channels worth of G.729.  We reset our
ATA186 boxes to use this encoding, and it seemed to be working.

However, we analyzed the data stream and saw that the ATAs were sending
about 4 kbps, while the stream from asterisk was still 64 kbps, which
says to me that asterisk is still using µ-law.

I looked in the sample sip.conf file and don't see any place to set the
encoding.  How do I do this?

Thanks...
