[Freeswitch-users] play file and stop play file on 2 channels

Hi there, I am trying to play a file to both channels of a bridged conversation through a socket. This can be done with: api uuid_broadcast <somechannel> <somefile> both However, I would like to be able to stop playing the file as well. This can be done with: api uuid_displace <somechannel> start <somefile> 3600 mux and api uuid_displace <somechannel> stop <somefile> But that one seems to work on only one channel. The other channel can mix its output but can not hear the file. Are there any other options? Thanks, Kees
