Hi list,
first of all: sorry for my bad english...
I'm new to Asterisk world... I'm using Asterisk-1.4.13 on Debian distribution.
I've tested with success loopback, mp4play, mp4save and IVR calling Asterisk with a 3G mobile phone.
Now I'm trying a 3G<->sip videocall (using a NEC-phone and X-lite running on Windows) but I think I'm confused about how to do this... I've read the mailing list archive, the pages on VoIP-info and the instructions on Fontventa but I don't understand how to write my dialplan, especially the order of the following exten...

This is needed for SIP-->3G calls (to make 3G video signalling in ISDN
SETUP message), but not needed for 3G-->SIP calls.
To bridge 3G-->SIP calls:
1. Make sure to have AMR codec installed (and configured codecs.conf ->
see readme from AMR codec)
2. in sip.conf allow videocalls and active h263p for the SIP peer
3. MAke proper bandwidth settings in XLITE/eyebeam:
deactivate the "zero touch bandwidth detection" and then in the
advanced section set the bandwidth to "DSL, Cable".
4. In eyebeam/xlite active the H263+ codec
5. For testing video calls it might also be useful to deactivate the
echo canceler in xlite.
6. Don't bother with outgoing calls unless incoming calls are working fine.

Xlite will probably send too much video bitrate so probably you'll see
video lagging and delaying from audio. In this case use app_transcode to
reencode the video to the correct bitrate.

Hi list,
first of all: sorry for my bad english...
I'm new to Asterisk world... I'm using Asterisk-1.4.13 on Debian distribution.
I've tested with success loopback, mp4play, mp4save and IVR calling Asterisk with a 3G mobile phone.
Now I'm trying a 3G<->sip videocall (using a NEC-phone and X-lite running on Windows) but I think I'm confused about how to do this...

h324m_gw is the function to receive incoming videocalls from the ISDN.
It creates a pseudo channel back into the dialplan with the extension
and context specified in the parameter.
This local channel has to be answered by h324m_gw_answer, which is just
like answer but signalling a VIDEOUPDATE to the h324_gw application so
no video is lost while setting the call. You can also use Dial instead
to call the SIP softphone.
h324m_call is for outgoing videocalls.
Best regards
Sergio

Hi sergio!
In my experience, using the "DSL, Cable" setting it works quite well. Of
course it requires configuration of the client.
I have also sent a patch to this list on 17.1.2008 (subject: announcing
bandwidth in SDP) which allows you to configure the bandwidth setting
announced in the SDP. Again there is a drawback: I only works with
xlite/eyebeam.

klaus
