[Freeswitch-users] Filler Music in Call Recordings

I'm trying to implement a feature that allows a user to selectively pause and resume a call recording via FreeSWITCH's event socket interface. The audio file should contain filler music for the duration of each pause operation. Is there any simple straight forward way to accomplish this? I would prefer avoiding the overhead incurred by using the conferencing module for this if possible. Thanks -JP
