[Freeswitch-users] Audio dropped using unimrcp tts.

Wed Feb 27 03:13:59 MSK 2013

Sorry for the delay.  I looked at the pcap and it confirmed my suspicion.
 The MRCP server doesn't reply with IN-PROGRESS until 1.35 sec of audio has
already been transmitted.

IN-PROGRESS tells mod_unimrcp that the request is has been accepted and is
being processed.  The module assumes the reply is immediately sent before
the RTP is streamed.
