Hi Bogdan,
Also, parsing into pseudo-variables that contain the SDP payload will allow simple logic to make routing decisions based on SDP content.

Hi Henning,

SDP is also signalling part (for media) and we are evaluation _only_ parsing functions, not functions to manipulate and do SDP changes.

currently there are 2 modules (nathelper and mediaproxy) parsing SDP and there is an intense demand for other SDP related functionalities (like being able to investigate SDP from script, etc); so makes no sense to have n modules, each implementing a parser.

We can have a parser in core and the modules will use it for whatever specific purposes.

If you make the parser a module, it will be rather a library than a module and it will create extra inter-module dependencies that we complicate thinks even more.

Thanks and regards,
Bogdan

Hi Ovidiu,

If this will be a collection of functions for parsing, I see no reason for not trying to include them in core. But for such a decision, more
info will be needed.


Hello,

integrating SDP parser functionality into the core would be the start for providing more and more SDP and media stream related functions in OpenSER.
I think we should try to stay on focus.
- OpenSER is a multi-functional, multi-purpose SIP server: router, switch, registrar, application server, redirect server, gateway, etc..
- OpenSER is only about signaling, but there are media adds-on

(some quotes of a VON talk of Bogdan)

In my opinion we're quite good in this area. But we've already enough problems to support SIP and all the strange implementations out there. I don't think its a good move to add to much SDP to our problem set.

So i think a module implementation of a sdp parser would make more sense.

Cheers,

Henning
