Is there a way to play the hold music on a channel in a ConfBridge when all the other channels are hold ?

I’m not sure to be clear, let’s describe a simple use case :

– channels A, B and C enter the same ConfBridge
– channel A is put on hold
– channel B is put on hold
– then I want to start playing the music on hold on channel C
– if channel B stops being held, I want to stop the music on hold on C

I looked at the options in confbridge.conf, but none seems to fit my needs. Any idea ?
