[Asterisk-video] h324m and SIP

Yes you're rigth I think only incoming media is dumped to a file.
I use object pointer to create the file name, it was the quickest way, I'll try to improve it in the future.

why do have h245 logs a different identifier - wouldn't it be good to 
have consistent naming?
