Thank you, Jaroslav!!!
I found an e mail sent by Alexander were he says that adding a new codec could
take about two days or a week. then, i thought it was not much difficult.
The encoder and decoder are already implemented because i am using voice Age
implementation. Then, i proceeded in a similar way as for GSM implementation
creating MpeG729 and MpdG729 clases, and other modifications in SipXmediaLib.
After doing this, i cannot make it ito work, thats why i thought that maybe i
am not modifying all the classes i should.
Any help appreciated.
Regards,
Mariana.

To be more precise, the timer and message aren't deleted if the timer is
never fired due to shutdown or sipxtapi reinitialization.
If timer fires and is received by handlemessage in SipRefreshMgr then it
and the message are deleted.
I think it would be sufficient to store all the timers somewhere (minus
those that got deleted in handlemessage) and delete them in destructor.
What do you think?
I noticed there is also SipRefreshManager class that should replace this
old buggy manager. When is that about to happen?

"Microsoft DirectX is used for video support. In order to build sipXtacklib
DirectX has to be installed
even if building "Debug_NoVideo" (this is most likely a bug in the build
system). The DirectX SDK can
be downloaded from Microsoft for free."
But I found my major source of problems. Something related to the "strdup"
use... I'm solving lots of
crashes by replacing strdup by malloc+strcpy.
Google it by "strdup _CrtIsValidHeapPointer"
Eg. UtlTokenizer.cpp module:
UtlTokenizer::UtlTokenizer(const UtlString& tokens)
{
// m_tokens = (char *)strdup(tokens.data());
m_tokens = (char *)malloc(strlen(tokens.data())+1);
strcpy(m_tokens,tokens.data());
m_tokenPosition = 0;
}
// Destructor
UtlTokenizer::~UtlTokenizer()
{
free(m_tokens);
}

Is sipXtapi's OsTimerTask the same as the one in the main sipX? There
have been a lot of fixes to OsTimer over the last year.

Alexander Chemeris merged all available sipxportlib revisions into
sipxtapi branch. Sipxtacklib isn't fully merged yet.
The problem isn't in OsTimerTask, but in SipRefreshMgr. I attached a
patch that solves the problem.
Timers (+messages) that got fired were deleted but timers that werent
fired because sipxreinitialize or uninitialize was called werent
deleted. This patch puts all new timers into a UtlHashbag, and removes
them from it once they fire.
From what I have seen in SipRefreshManager.h it seems SipRefreshMgr
will be replaced so this patch should be sufficient.

Subject: [sipxtapi-dev] Help for G729 patch
Message: 6
Hi,
I am working on a patch for sipXezphone, adding support for g729 using the
encoder and decoder from Voice Age. I have been trying but i still cannot make
it to work..
My question is: does anyone know which clases of the sipXezPhone shuld I deal
with? I am not very familiar with the whole project. Maybe someone knows some
of the classes were i should modify something so as to add another codec.
Of course when i finish this implementation, i will send it to all of you :)
Thank you very much!
Mariana.

Subject: [sipxtapi-dev] How to use SipXtackLib as a SIP stack??
Message: 7
Hi all,
I'm developing a soft phone with NET-BRICK as a SIP stack and using
sipXPBX as server.
So I want to replace the NET-BRICK (sip stack) by a sipXtackLib.
I have some questions about using sipXtapi and sipXtackLib:
1. Could I use sipXtackLib as a SIP STACK? I have searched around, and
there is lack of information about using sipXtackLib.
2. I hope I could use sipXtapi for soft phone but I don't want to use
the media framework from sipXtapi. Could I using sipXtapi without
media framework? I want to control the media packets.
Thank you very much.
Regards,
DBQ.

Yay, this might not be so easy if you think it can be done by modifying
sipXezphone. Alexander Chemeris wrote an email which is in the
mailinglist maybe 2 months back about adding a new codec. You basically
need to add a wrapper class for decoder + encoder for sipxmedialib +
some more modifications.
I do not consider sipXezPhone worth adding any new features except maybe
functional video (which maybe works partially in sipxmediaupdate
branch), as its moreless only a demonstration that sipXtapi really works
(on my PC it didnt work at all until I fixed some bugs). I have a
functional softphone using sipXtapi that can actually be used as a
softphone not only as a demonstration and might contribute it under GPL.
It uses also wxWidgets but 2.8.2, user interface is made in
dialogblocks, its loaded during runtime from XRC xml file so it supports
basic skinning that xrc alllows (reorganization of positions and sizes
of widgets, bitmaps on bitmapbuttons - i made a custom
togglebitmapbutton, changins texts, adding new bitmaps, changing various
icons), unfortunately full skinning is not possible as projects like
wxSkin dont support the widgets I needed, it has call history, contact
list with groups support, multiple sip profiles, multiple lines (lines
are real sipXtapi lines, so you can have multiple calls on the same
line, so to do an operation on a call you need to select a call not
line), conference manager, multiple languages support basically all you
need to use it as a softphone. SipXtapi functions that take too long to
complete (initialization ,reinitialization, uninitialization, line
registration) are called from another thread so you get no freezing
during change of sip profile (I do sipxreinit as I do not consider
sipxtapi stable enough to just unregister lines, change sipproxy and
register lines).
There are still some serious bugs in sipxtapi or sipxcalllib that I need
to fix until sipxtapi can be really considered reliable for me:
1.) Crashes during reinitialization of sipxtapi. Crash in select in
SipClient while other thread does close on the same socket. If you have
dual core processor the this is problematic. This crash is inside select
winsock function, regardless of the version I use. Currently this is
solved by my patch/hack not using blocking select, it uses 200ms
timeout. But this is not acceptable. There are 2 more crashes related to
reinitialization, which have been fixed by my patches (one is in
previous post, and 2nd is in jira)
2.) Split on conference call does something to it and no more call
events are received for it. This has to be fixed.
3.) Sometimes line registered event is missing, this has to be fixed.
4.) I need to have a look at audio during call, I think something is not
ok here.
5.) There is no simple way to implement custom ringtones in sipxtapi.
You can only play wav files in a call which is not good. If you have
more calls and want to have custom ringtone, you have to play the
ringtone on the call in focus, not on the call in alerting state
(otherwise u dont hear anything).
6.) Is SRTP working in sipXtapi? Is it worth spending time to get it
working or is it too buggy?
