[OpenSIPS-Users] OpenSIPS 3.2 B2B tutorial pre-paid example

[Răzvan Crainea]

Hi, Xaled!

No, there should bot be an SDP, because you don't have an SDP (the media 
server is gone, and you don't know the callee's SDP). Instead, the 
module is doing a late negotiation to find out advertised caller's SDP, 
and present it to the new callee.

Best regards,
