Hi All,
I want to use PJSIP for integration with our RTP.
Please address following queries:
1. Can i use PJSIP for integrating with third party media application?
2. Does PJSIP stack support Multithreading?
3. Does PJSIP support Multihoming?
Thanks & Regards,
Avnish Kumar Tyagi

Hi Ramzi,
Here are some notes from the log file:
1. The log file says the call was using G.722 codec which may not be
preferred. To completely disable G.722 please specify "#define
PJMEDIA_HAS_G722_CODEC 0" for WINCE build in the
config_site.h/config_site_sample.h, or you can always lower the
priority of G.722 using pjsua_codec_set_priority() in the
pjsua_wince.cpp.
2. There seems to be a bug in g722.c (error PJMEDIA_CODEC_EFAILED),
the patch below should fix it (please try it and drop some feedback,
since I haven't been able to reproduce the error).
Moreover, assumed caller and callee share the same source code:
3. The caller was not offering PCMU/PCMA in the INVITE, it seems to be
disabled on purpose since it is enabled by default.
4. GSM seems to be there, it just had a lower priority than G.722, so
it was not chosen.

Hi,
We are trying to port PJSIP to iphoneOS. We are using Xcode tools. We see
lot of errors referring to iphone OS header files.
As a first step we ported PJSIP to MAC OS X 10.5.2. This was a easy task
as we used the configure tool. However we could not find any documentation
on porting PJSIP to iphoneOS at PJSIP site.
Please forward me to a link which gives information on porting PJSIP to
iphoneOS.
Thanks & Regards
Anand

It's generally a bad idea to show modal dialog on the callback because
that will block the stack. Having said that, the stack should not
crash because of that, so the crash was caused by something else
(possibly in the application). It's impossible to know what's wrong
without seeing the call stack trace.
Cheers
Benny

Based what we've been focusing on recently (mainly to make existing
features (audio and NAT traversal) better, more robust, more stable,
and works on more platforms), I've got the feeling that probably we
won't have time to do video this year. But we'll see. For now, I'll
just remove it from the FAQ to avoid disapointment.

What platform are you running this on? Can it handle more than one calls?
