<pre wrap="">hello Klaus
Finally i managed to do some tests
For h324m to work i had to do the following
I removed asterisk 1.4.15 and used asterisk 1.4.21.1 with the patch as
for your instructions.
I used libpri 1.4.5 and patched it. I used zaptel 1.4.12.1 because on my
debian machine i could not compile 1.4.11 (there is a bug about kernel,
don't know much)
I compiled with my asterisk amr codec, app_mp4, app_transcode, app_rtsp
Now almost everything seem to work.
These are the scenarios i tested
1. 3g --> pri --> asterisk --> mp4play
works like a charm video and audio
2. .call file --> asterisk --> pri --> 3g
works like a charm - video and audio
3. sip softphone bria --> asterisk --> pri --> 3g
video works fine, no audio, i noticed the following errors on
different tries
a. Got SIP response 415 "Unsupported Media Type" back from 10.0.0.21
b. rtp.c:1286 ast_rtp_read: Unknown RTP codec 126 received from
'10.0.0.21'
c. chan_sip.c:5506 process_sdp: No compatible codecs, not accepting
this offer!
i suspect that bria might not have required codecs
4. 3g --> pri --> asterisk --> sip
again caller can see my video but i cannot see the caller, no audio
Tomorrow i want to try ivvr, and let you know.
I havent managed to try app_rtsp as i dont have anything to stream from,
would vlc work?
i havnet managed to use transcoding as again i dont know how to use it,
any example or any help?
Thank you in advance for your replies, hope you can help me solve the
audio problem
Best regards, to all
Dinos

The production system I have is still running asterisk-1.4.21.1 with
libpri-1.4.5 and zaptel-1.4.11.

I do not know if newer/older versions work fine too.

So, what happens exactly - does Asterisk crash?

<br>
what about reloading the zaptel kernel modules? (rmmod,
insmod/modprobe)
<br>
<br>
<blockquote type="cite">Also i read about a patch in libpri in order
to make outbound 3g calls,
<br>
which in fact is what i want to do. I havent applied any patch to

libpri. Should i and if yes where do i get it
<br>
</blockquote>
<br>
The patch is onyl necessary for proper signaling of outbound calls.
Thus, in your case where you test with inbound calls there is no need
to patch yet.

project, i am having difficulty to find dialplans to test, like how to

use app_transcode and how to set up test environment e.g. how to make

sip to 3g and vice versa

<br>
True.
