well, thanks ;) this i thought for myself too, because it would be the 
easiest way. my first guess was to use the function CHANNEL():
R/O 	*videonativeformat* 	format used natively for video


This sounded just like the information i wanted. But
exten => 555,n,Set(video=${CHANNEL(videonativeformat)})

keeps being empty, whatever call i make (with video or without video).

Other variables i tried were:

${ANI2}                 * The ANI2 Code provided by the network on the 
incoming call.
                        (ie, Code 29 identifies call as a Prison/Inmate 
Call)
${CALLTYPE}             * Type of call (Speech, Digital, etc)

ANI2 keeps being 0 and CALLTYPE keeps being empty ...

any other variables i overlooked so far that might proof useful ?
