Hi,
Just wanted to touch base on the parser to find out if you are still pursuing this.
it is still on my todo list, however didn't make it in the upcoming 1.5.0. Ovidiu Sas did some commits to the SDP parser and I know couple of others using it with success.
Please open a feature request at: http://sourceforge.net/tracker/?atid=743023&group_id=139143&func=bro...
It is easier to track and not forgot about it for the next release.
Thanks, Daniel
I am in the mind of purchasing some Cisco equipment to do the Sip-MAP gateway from a GSM network. I have someone else from the OpenBTS with me on this. The object is to provide a full fledged sip based routing of voice, sms and multimedia calls from gsm handsets to BTS with a Sip server backend.
Cheers, Abdul Hakeem

Hello everyone,
Feel free to set $OSSPROXY to whatever you like = Kamailio/OpenSIPS/OpenSER (for those of you who can't let go).
$OSSPROXY is my favorite SIP toolkit. In addition to being an excellent proxy and registrar it serves as a platform to do SIP mangling and wrangling. With that in mind let me propose a crazy idea...
How hard would it be to get $OSSPROXY to be able to parse what is commonly referred to as SIP-T (RFC 3372)? I understand $OSSPROXY has no business getting too involved in the SDP but I feel it makes sense in some instances (like this one). What if I want to make a routing decision based on an encapsulated ISUP parameter of some sort? Who knows what it could be!?!? Maybe there are some other uses but that makes the most sense and seems to be the most practical. It should be possible to develop an $OSSPROXY module to:
- Use the SDP parser to find the ISUP SDP part:
http://www.kamailio.net/dokuwiki/doku.php/development:sdp-parsing
- Pass that part into a "real" ISUP parser (if necessary). I couldn't
seem to find the perfect library but perhaps something like this could work:
http://www.openss7.org/isup.html
- Make the ISUP parameters available via AVPs, pseudo variables, etc
for use in the $OSSPROXY script.
I don't really have a need for this but it seems like it could be cool. Am I nuts?
I would expose the body as a dynamic structure, so components will be accessible in the script, e.g. (naming schema just for example),
if($body(0=>content-type)=="application/sdp") { if($body(0=>m=>type) == "audio") { } }
Based on the available content type parsers (sdp, isup), the structure has different attributes.
Cheers, Daniel
