Asterisk 13 and Mixmonitor - empty files left behind

Dear all,
running Asterisk 13.12.1, and using mixmonitor() to record conversations, with the b flag to only record when a bridge has been created / established. Unlike with other versions of asterisk that i am running it seems that with this one, mixmonitor leaves behind empty wav files when the call is not answered. One example is that when receiving a call into a queue, which then rings out a number of people, an equal number of empty recording files is created but never cleaned up.

Does this sound like a bug? or is this the expected behavior of mixmonitor when it is called from the dialplan?


Just upping this up in case anyone has any suggestions or has encountered the same issue before

upping this one more time :slight_smile:
