Hi Michael, this is the behavior I've seen if there's a bad IANA name in the rtpmap for G729 and from your logs it looks like this is the case - G729a is being presented (a=rtpmap:18 G729a/8000)

Turn on bad IANA name support (http://wiki.freeswitch.org/wiki/NDLB#NDLB-allow-bad-iananame)  in your SIP profile(s).

<param name="NDLB-allow-bad-iananame" value="true"/>

Regards,
Steve

Hi Kristian,

 Thanks for your input, please find trace attached as requested with sofia SIP trace on.

 I have gone through it again & don't see the SDP arriving wrong.

 Let me know what else I can do to assist.

Kind Regards,

Michael

Can you post a console log with siptrace enabled:

sofia global siptrace on

It looks like FreeSWITCH is getting that SDP from somewhere else.  0
as the port number, G729 as dynamic payload type 96...  It's
completely messed up and I've never seen FreeSWITCH generate an SDP
like this.
