[Users] xten to sipura compatbility issue

[Craig Peacock]

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
