Codec G729A implementation

Freddy Montas
Level 1
Level 1

Hi, im currently using a Cisco 2821 as a CISCO UBE between to endpoints with codec g711ulaw.  I want to migrate to g729a.  I have installed all the necesary pvdm modules, but i think i might be missing something in the config.  Everytime i change the dialpeer to use the g729r8 codec i get the following error:

//209/9F8ADEC68233/SIP/Error/sipSPICreateOutboundSDP: Error in creating an SDP for the outbound call - Check for supported codecs

and

SIP/2.0 501 Not Implemented

please help.  Thanks

Freddy
