Sorry, I misspoke :
I do a MixMonitor on a bridged channel so MixMonitor record both in and out channels.
I would like MixMonintor to stop recording one specific channel of the bridge
scenario : a call comes in (channel pjsip/trunk-xxxxx), the dialplan dials ext 300 and bridge the call so we have pjsip/trunk-xxxx bridged to pjsip/300-yyyyy and MixMonitor recording both.
I would like to stop recording pjsip/trunk-xxxxx and continue recording pjsip/300-yyyyy
MixMonitor is recording audio flowing for a single channel, specifically generally each direction. It’s not recording each channel itself. If you stop MixMonitor then you stop the recording. You’d need to start a new one up on the other channel.
You can choose when MixMonitor is invoked to record them separately. You can’t alter that afterwards. The most I can think of is using MixMonitorMute to mute a specific direction so that direction is no longer recorded.
