Re: [Sofia-sip-devel] How to generate a initial local SDP using sofia-sip API?

btw, telepathy-rakia (formerly telepathy-sofiasip) provides
a more complicated example of how to generate the local SDP in
a more dynamic fashion (depending on which codecs are available/configured):
http://cgit.freedesktop.org/telepathy/telepathy-rakia/tree/rakia/media-session.c#n1759
But yup, still using the same mechanism.

That's a good question. In short, no, there's really not much
support for generating SDP element by element. The SDP module does provide
a parser and printer, but support for modifying the parsed SDP is fairly
limited:
http://sofia-sip.sourceforge.net/refdocs/sdp/index.html
So at least I've found it much easier to just create the template
SDP as text and fill in the needed dynamic elements. In theory the SDP
module could be extented, but I'm not sure if it's a worthwhile
effort... :P

[Sofia-sip-devel] ANN: sofsip-cli moved to git
Hello all, I just pushed the full sofsip-cli repo from darcs to a new git tree at: https://gitorious.org/sofia-sip/sofsip-cli PS The old darcs repo still at http://sofia-sip.org/repos/sofsip-cli/, but won't be updated anymore.

[Sofia-sip-devel] NOTIFY sip frag set to 503 when receiving 407 Invite response
Hi, when performing an attended transfer, when the transfer destination sends a
407 to the INVITE with replaces generated by transferee, a NOTIFY with 503
sipfrag is sent to the transferrer. Code is here in nua_session.c
in function nh_referral_respond. The transfer destination is in different
domain. The resulting NOTIFY 503 sent to the transferrer makes him think the
transfer has failed rather than just being in progress. Is there some reason
for this or is it a bug?
if (status >= 300)
status = 503, phrase = sip_503_Service_unavailable;
snprintf(payload, sizeof(payload), "SIP/2.0 %03u %s\r\n", status, phrase);
if (status < 200)
substate = "active";
else
substate = "terminated ;reason=noresource";
nua_stack_post_signal(ref->ref_handle,
nua_r_notify,
SIPTAG_EVENT(ref->ref_event),
SIPTAG_SUBSCRIPTION_STATE_STR(substate),
SIPTAG_CONTENT_TYPE_STR("message/sipfrag"),
SIPTAG_PAYLOAD_STR(payload),
TAG_END());
Regards

Based on logs, the call is succesfully setup, so you should be able to see RTP packets flowing. My guess is that something is wrong with how gstreamer pipeline interacts with your (ALSA) sound device. sofsip-cli does not have any diagnostics for this, so you need to use gstreamer debugging to figure out what is happening. To get started, take a look at: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gst-running.html .. and the various GST_DEBUG options.

I think it is a bug, the stack should check if the request is restartable. --Pekka -- Pekka.Pessi mail at nokia.com -- Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf ___ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
[Sofia-sip-devel] Integrating sofia with other event loop libraries
Hi, I noticed sofia has its own event loop and there is integration with glib event loop. It is possible (and easy) to integrate sofia with other event loop libraries? I'm interested in integrating it with libev specifically. If not (possible or easy ;), is it sofia thread-safe? Can I enqueue sofia events into my own loop and thus do the processing in another thread (calling sofia API from another thread, different from where sofia event loop is running)?

[Sofia-sip-devel] Setting sofia-sip Source Port
Hello, I am setting my contact address to specify port 5061 (for TLS), but a wireshark trace shows the message being sent with a source port of 1025. This is confusing the Redcom server. How can I make sofia-sip send the message with the same port as is in the contact header?
