[Asterisk-video] app_h324m questions

[Klaus Darilion]

Hi Marcin!

Thanks.

Now I have also updated app_h324m to use AST_FORMAT_AMRNB instead of 
AST_FORMAT_AMR (although I think this should be irrelevant as they both 
use 1<<13).

Nevertheless, Asterisk crashes when accepting the Video Call on the SIP 
phone :-(

regards
klaus
