Freeswitch G729 pass through for Linksys Sipura

Submitted by devblog on Sun, 11/04/2010 - 17:40

After a rather long thread on the Freeswitch mailing lists I managed to get G729 passthru working on Freeswitch (svn 17048).

Requirements

mod_g729 should be enabled in modules.conf.xml.

In vars.xml G729 should be added to the codec prefs, or should be the only one if you are sure the provider(s) support G729.

  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,PCMU,PCMA,GSM,G7221@32000h,G7221@16000h,G722"/>
