Re: [Serusers] Bandwidth parameter modification (b:) from ser.cfg - sr-users

4 Sep 2006

Ah!
Try:
http://www.ietf.org/rfc/rfc3556.txt?number=3556
for description of b-parameter in SDP.

  Hi!
 I will re-try with nathelper, mediaproxy and mangle modules ...... But 
 till now I haven't found anything about b parameter. About bandwidth 
 types I also don't now what that mean, I have written it down because 
 I have read it in some articles ...

 My problem is that I have one application that exchange a b parameter 
 (b=CT 140) during INVITE and isn't able to work with any other SIP 
 based application. And the only suitable explanation we have found is 
 that the b parameter is disturbing our communication.

 So thank you very much! We'll try something else!

 Best regards,
 Victoria

  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.

  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!

 Best regards,
 Victoria
