[Freeswitch-users] Issue with a=fmtp:18 annexb=no

[Sam]

Hi,

We are facing an issue with a=fmtp:18 annexb=no.

Here is the call flow,
Cisco CUCM ->  Cisco Cube -> FS

Cisco is expecting in 200 OK ,

   m=audio 28820 RTP/AVP 18 101 13
   a=rtpmap:18 G729/8000
   * a=fmtp:18 annexb=no*
   a=rtpmap:101 telephone-event/8000
   a=fmtp:101 0-16
   a=ptime:20

But fs is generating without  *a=fmtp:18 annexb=no*
   m=audio 28820 RTP/AVP 18 101 13
   a=rtpmap:18 G729/8000
   a=rtpmap:101 telephone-event/8000
   a=fmtp:101 0-16
   a=ptime:20

Because of that calls are getting fail.

I am not getting where should we change setting to include that line.

Please help me to resolve that issue.

Thanks in advance.
