[OpenSIPS-Users] codec_delete_except_re SDP Corruption

[Kneeoh]

Sure, I'll get that for you. I've got some additional data that may answer your question. The problem seems to occur when the codec being removed is at the end of the SDP offer. So you'll get something like

0 18 101 19 in the media description line and 19 is the one you remove. It leaves the space after the 101, which is causing the problem.

Hello,

Is the codec deletion the only change you do over the SDP (codec related) ?

What opensips version are you using ?  Also, could you post (privately 
is needed) the exact original and modified SDP ?
