[Asterisk-video] Video stream delayed (SIP->3G)

[Borja SIXTO]

Hi Klaus and Sergio,

That is right, the Soft Phone Kapanga generate a bandwidth greater that 
80kbps...
The Bandwidth limiter is not efficient.

For information :
- with x-lite, it works well but the video sending is not easy to 
activate (you must push the button send video, and generaly I shoud 
close and open the left tab).
- with kapanga, I have bandwidth problems (sometimes it works, I am 
going to contact the Kapanga support).
- with intellivic, I am making tests, but I think the payload 
h263/rfc2429 enabled generate h263+ video stream and the 3G phones don't 
show the video.

I am using the app_transcoder but I have some problems...
I will post a specific message for that.

Regards and thanks,


Tech from i6net
