[OpenSIPS-Devel] question about sdp

[Răzvan Crainea]

Hello!

If you only need the SDP body, you can use only the "$rb" 
pseudo-variable. Only if you need the "a=" line from the SDP you should 
use the sdp transformations, but I don't think your OpenSIPS version 
supports them. What version are you using?
