[Asterisk-video] h324m and SIP

[Klaus Darilion]

Thanks for all your input: Meanwhile I have manged to run Asterisk 
1.4.17 and rev207.

I test the h324m application bridging to SIP.

My experiences:

3G-->h324m_gw---SIP+GSM--->Cisco-gw--->ISDN: audio is fine
3G-->h324m_gw---SIP+GSM--->eyebeam: audio SIP->3G has drop outs
3G-->h324m_gw---SIP+G711-->eyebeam: audio SIP->3G has many drop outs

Here I suspect maybe some issues with bad conversion to AMR inside 
Asterisk. What results do you have?

Video:
Video from 3G to SIP is working fine (eyebeam).
Video from SIP to 3G is bad - most of the picture is just black. Here I 
suspect maybe a problem if the bandwidth of the video received from SIP 
is to big to fit into the H223 channel.

Sergio - how is multiplexing between Audio and Video handled - das Audio 
have fixed bandwidth or my too big video bandwidth also disturb audio?

Are there somewhere bandwidth statistics in log files from h324m_gw or 
libh324m?

thanks
klaus
