[asterisk-dev] Dialplan pre-bridge handlers

Hello Jim,

thanks for the reply. Consider the following scenario:

Joe calls Mary and asks to speak to Jill. Recording a call with Mary is 
allowed, so recording on Joe's channel is turned on. Mary makes an 
attended transfer to Jill. Both Mary's channels are hung up, and Joe's 
and Jill's channels are now bridged. Recording a call with Jill is not 
allowed, so StopMixMonitor should be executed on Joe's channel before 
bridging. How can Local channel help me do that?
