[Freeswitch-users] Ringback, MOH or file playback while executing dial plan instructions

Hi all, Is there no way to force a 183 in a session and play a ringback or MOH while executing other dial plan instructions? Basically, I’ve gone around trying instant_rinback=true, ring_ready, gentones, etc… No luck. If I bridge my channel to loopback/wait, sure enough it works. What I need to do is play a ringback or some MOH while I carry on executing my dial plan instructions. The 183 is a nice to have but I don’t mind if the channel is answered. Thanks, Emrah
