Victoria, SIP and SER do not really look at the SDP payload (ideal world). However, nathelper, mediaproxy and the mangle (have a look at it) modules allow you to do tricks with SDP fooling the user agents involved in the dialog in some way (for example by making both talk to a rtp proxy server). As for bandwidth types (not sure what you mean here?), maybe somebody on the list knows of something, but it's slightly off topic on this list. g-)

Hi!

I am a beginner with SIP/SER systems. I have been having a look into ser.cfg, in order to modify some SDP parameters, for instance, fix_nated_sdp to change connection IP, and I have found enough information to do it. But, now, I am traying to change b parameter, but cannot find where to do it (Which module manage it?). I am also looking for a document with a description of all bandwidth types (CT, AS). Could you tell me something about this stuff, please?

Thank you very much in advance for your help.

I am very sorry if this is a very silly question!
