1. G729 Codec
2. Install G729 On Asterisk

FreeSWITCH is not the offending party here, but the device that is sending G729 as G729a. The correct encoding name assigned to this codec by IANA is G729 not G729a. To fix interop quirks like these FreeSWITCH has. 这是一个 freeswitch 的 G729. //github.com/typefo/mod_g729.git $ cd mod_g729 $ make $ make install freeswitch. Codec Interfaces -->
