[Users] xten to sipura compatbility issue - sr-users

21 Jul 2006

Ray,

The problem is in the Sipura's SDP :

...
  a=rtpmap:18 G729a/8000. 
My understanding of RFC3551 is that the encoding name "G729a" is not 
compliant. Therefore when the Sipura sends this to your Softphone, the 
softphone which is compliant to RFC3551 rejects the request and you get 
a BYE.

Maybe force your Sipura to use G711a/u.

Regards,

Craig Peacock

  I have set up both xten and sipura, I want to test
onnet calls between 
 them.  I am fine with xten eyebeam  to xten eyebeam,  and sipura to 
 sipura, both scenario works fine.  when I do xten to sipura 2000, it 
 rings and when pick up, xten sends BYE right after ACK.  I've tried 
 1.0.1 verson and the CVS HEAD, happens to both version.  did anyone 
 encountered the same problem?

 thanks

 Ray
 ps.  debug attached
