[Freeswitch-users] Audio "clicks" between playback of audio files

I'm implementing an IVR solution for FreeSWITCH, but I have a little problem with audio playback. I'm just calling into application park, and then handle the flow using the event socket.

All my audio phrases are .PCMA (8KHz a-law), and I play lots  of files after eachother. Between each file I can sometimes here a little "click", even though I'm 100% sure that this is not from my files. My guess is that it might be caused of the fact that no RTP is sent at all when the phrase is not playing. If I merge the files together before playing them it sounds just fine.

Is it possible to make FreeSWITCH send silence frames, even when not needed? I know this is a waste of resources, but it will still make the solution sound much better.
