[pjsip] stop recording when silence is detected

[Wayne Waldner]

It is common in IVR type applications to allow recording to stop automatically if silence of (n) seconds is detected.  When using the File Writer (Recorder), can anyone suggest a way to stop recording when a given amount of silence has been detected?  I presume one could use the Adaptive Silence Detection algorithm, but not sure if I am on the right track on this.  If the Silience Detection algorithm is used, would one have to record to memory buffer and ‘pipe’ the pcm data into the algorithm?  Perhaps a special media port has to be created to implement this functionality.  Any ideas?
