Hi all,
This is a newbie question which I hope has an easy answer :-)
I receive a SIP SUBSCRIBE message in an NTA agent processing the calls
in a stateless way (no call legs). I use nta_msg_treply to send the 200
OK response, but I would also need to initiate an outgoing transaction
to send a

More than probably, it's my fault, but I am getting tons of memory leaks

reported by valgrind like this:
==31415== 8,795,284 (1,302,928 direct, 7,492,356 indirect) bytes in
2,692 blocks are definitely lost in loss
), and when freed, it is
just marked as freed in the home (so the home won't be smaller). Is this
home memory ever going smaller? Maybe (probably) I am missing something.
Any hint on this?
Thanks,

If it's just printing I/O SIP messages, you can also export TPORT_LOG=1
before running your app, or include the following code:
setenv(TPORT_LOG, 1, 1);
I also have a sofia-sip log redirection to my own function:
su_log_redirect(NULL, __sofiasip_logger_func, NULL);
And this is my
I see that nta_leg_magic() is defined like this:
nta_leg_magic_t * nta_leg_magic (nta_leg_t const *leg, nta_request_f
*callback)
Return application context for the leg.
But what's the purpose of including the callback function in the
request? Shouldn't it be enough with passing
In a brief, is making the home of NTA agent thread-safe enough for all
those situations?
Unfortunately no. The nta functions are thread-safe in the mean that
they do not use any shared global data, the nta objects like nta_leg_t
or nta_agent_t are not thead-safe.

Sofia SigComp package is Nokia proprietary code, it is not publicly
available. There is a GPL sigcomp packages available, however, some
plumbing is required in order to fit it with Sofia.

Hi all,
In a stateful NTA, I am getting SIP SUBSCRIBE from a sip client using

to make it use TCP.

Hi all,
I'm using su_msg_r objects to pass information between clones, using
`su_msg_create()' and `su_msg_send()'. These functions are perfect for
inter-clone communications (with threading enabled, so inter-thread
communication at the end).
Now, I may want to send a su_msg_r object to a given
In my case, no such reply/report is needed, as I just need to dispatch

su_msg_r and nothing else, so I was wondering if this other approach is
acceptable:

* Then, instead of `su_msg_send()', use `su_msg_send_to()', as this last

Hi all,
I am trying to discover why a call to nta_outgoing_tcreate() returns NULL.
It probably is due to a wrong tag, but the thing is that even if I enable
the maximum logging level, I don't get any error message explaining what's
wrong.
I set SOFIA_DEBUG, NTA_DEBUG and SU_DEBUG environment

my nua application has to do something if it receives a P-Asserted Header

(using sip_p_asserted_identity), because the SIP

I prepared a small patch (attached) to current darcs implementing a new

Hi Pekka all,
We just faced an issue happening only in 64-bit architecture, and found that
it was already fixed by FreeSWITCH guys in their own sofia-sip repo:

It seems the fix is not included in the official repo, which would be good
to have.

Hi Pekka all,
Is there any difference in using SIPTAG_END() instead of TAG_END() as
end-of-list terminator in a nta_incoming_treply() ?
Actually, SIPTAG_END() is segfaulting in a 64bit architecture, while
TAG_END() is not.
Cheers and thanks,

Hi Pekka all,
Would be a good idea to explicitly say in the documentation of su_home_new()
that the allocated memory chunk is also zero-initialized, as it is a call to
calloc().

HI Dave,
I am writing a fairly simply stateless redirect server. It is
multithreaded, where the main thread creates the root task and runs the
thread loop, and receives incoming SIP invites. If I simply respond to the

No, internally NTA stores all legs for all dialogs.
