[SR-Users] SDP c= IP doesn't get rewritten

Thanks Daniel,

after messing around with msg_apply_changes() I gave up because it screwed up my Record-Route: so I ended up with rtpproxy_manage("...", "IP ADDRESS") which temporarily solved my problem. For now I'm facing firewall issues but this is completely different story.

Thanks again for the hint !
Daniel

Hello,

upgrading will not help. The best is trying to avoid using the two operations over the same message. Alternative is to use msg_apply_changes() in between them.

It is due to internal architecture of how changes are done to the sip message. They are not applied immediately -- see more details here:

Cheers,

If you're going to recommend to upgrade/or use something else - this is not feasible for some weird reasons. Is this a bug or just my misunderstanding how to use this function ?

thanks

Hello,

are you using a rtp relay (e.g., rtpproxy)?

Cheers,
Daniel

All,

I am facing problem with rewriting SDP part of the INVITE, in particular following is in my configuration:

#!subst "/RTP_INT_ADDR/10.96.173.15/"
#!subst "/RTP_EXT_ADDR/168.7.24.17/"
#!subst "/BOT_RTP_ADDR/10.96.173.52/"

subst_body('/RTP_INT_ADDR/RTP_EXT_ADDR/g');
subst_body('/BOT_RTP_ADDR/RTP_EXT_ADDR/g');

and this is what I ended up with:

c=IN IP4 10.96.173.15168.7.24.17

Apparently 2nd rule doesn't work rewrite, it's doing append instead. What I want to achieve is : if SDP part contains BOT_RTP_ADDR -> rewrite it. In case SDP part contains RTP_INT_ADDR-> rewrite it, so 2x if.

I have tried to use sdpops module, it's coring in my case and I have a reason to not upgrade, I just can't. Any other ideas how to handle my problem ?

Thanks
Dan
