[Asterisk-Users] sniffing bridged video call on zap channels

[Klaus Darilion]

Hi all!

I've sucessfully bridged an 3G-H324M video call through asterisk using 
ISDN PRI zap channels. Now, I want to monitor the call and dump it into 
a file for later analysis of the H324 call setup.

I tried to use the Monitor() application, but I breakes the session - 
looks like it does some transcoding which breakes the transmission 
between the bridged zap channels. Further, AFAIK, it does not support 
writing raw data into a file.

Is there a way to dump the whole conversation in raw-format (bit by bit 
as it is received on the zap channel).

thanks,
klaus
