Also, I wonder which is the supposed way to fill an SDP from scratch. I can't see any specific function for doing that (e.g. add a connection, add a media etc.) and doing it manually is tedious. So I suppose that the supposed way to create an SDP from scratch is to write it down in its textual form *then* convert it using an sdp_parser_t, otherwise maybe I have to use some higher level function not provided in the sdp module (soa?). Am I right?

Another solution could be to pass around sdp_parser_t rather than sdp_session_t, then use sdp_session() to get the sdp_session_t from the parser and free both parser and session with sdp_parser_free(), do you think this is an acceptable solution? But still this looks like a strange solution and not particularly convenient (why to pass around the whole parser if what I need is just the session?), and is the reason for which I was looking for an sdp_session_free() function. I guess you don't really want to keep the parser state. A home is a pool for allocated memory in the Sofia stack, so yes, you need to pass it around to wherever you free the sdp_session_t. Thanks for the reply Mikhail. So if I understood it correctly I need to keep an home just for every sdp_session_t. So my next obvious question is: it would be possible to change the API and implement an sdp_session_free() function? The sdp_session_t could inherit the home of the sdp_parser which creates it, or if created from scratch (sdp_session_create(home)?) it would require an home as argument. Not sure if this is possible to do without to break backward compatibility. And still I have the sensation I'm doing something very strange with my code, if no one ever had felt the necessity for a such facility (I'm using the sdp_session_t to store an SDP in a C-language-friendly manner)...

[Sofia-sip-devel] tcp transportation using only one connection
Hi! When using UDP for transportation the sofia-sip stack uses the same socket (same src port) for all outgoing logical connections. This is not the case with tcp. If I want to do a REGISTER with my proxy/registrar, the sip stack creates a new tcp connection (with some arbitrary src port) but does not insert this arbitrary port into the contact header. Instead, the contact header's port is set to the one of the tcp-server socket listening in general at port 5060. Hence, the registrar opens a new tcp-connection to my UA. So could someone give me please a hint how to force the REGISTER-socket to a port of my choice or how to get the real port into the contact-header-line? Or is there any other possibility to have only ONE tcp connection to my register with the UA always being the client? thanks for any advice, cheers, flo - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
[Sofia-sip-devel] Simple NTA processing...
Hi Folks,
I need to implement a sip registar and presence server into an
existing application...
My first step down this road was to attempt to build as simple a
registar server as possible in order to aid understand sofia-sip and
sip in general.
I have come up with the following code, which seems to let me
register, but I bet invalid status from callback messages... I am not
sure what this means or where I should be going to find a clue to the
solution.
Can anyone assist?
Any other comments on how I am using NTA are apprecated, but please
keep in mind this is toss away code and is not meant to be complete.
:)
The output I am getting is:
Got Root
Got Agent
Got Default Leg
Incoming Request
