hi ,

Hope everyone had a good Christmas and will have a wonderfull new year ahead.

I have some doubts related to Signal Descriptor handling.

1. 

  RFC Section 7.1.11 states that

“Production of a Signal on a Termination is stopped by application of 

   a new Signals Descriptor, or detection of an Event on the Termination .”

Also,

“A new Signals Descriptor replaces any existing Signals Descriptor.”

Q: The MG maintains the current signal descriptor until a 

new descriptor is not sent by the MGC. But, after the termination 

finishes the  playout of the signal or an event is detected and the

 signals are stopped, the signal descriptor remains the current one

 with MG until new one is received as according to the rules we cannot remove it until new signal descriptor is received.

 But my doubt is why should we maintain this descriptor since it has already become deactivated(either by finishing playout or event stopped it) and MGC cannot instruct MG to use it further ??.

Thanks ,

regards ,
