[Freeswitch-users] G729B and mod_com_g729

Thu Dec 9 20:39:00 MSK 2010

Hey Guys,

When using mod_com_g729 I found out that FreeSWITCH is rejecting G729B
in this form. I know about annexa=no parameter, however have seen
quite some UAs sending it in this form. Any work-around I can make
FreeSWITCH accepting it?

My FreeSWITCH version:
FreeSWITCH version: 1.0.head (git-) checked out somewhere in the
middle of October.
mod_com_g729: fsg729-167-installer
