Hello! Need your help!
I have next scheme of RTP processing:
rtpengine <-> caller freeswitch <-> robot freeswitch.
And next scheme of call:
1. Caller make an outgoing call (1) via rtpengine
2. On answer caller make an outgoing call (2) to robot and bridge it with
I have a problem with RTP stream rtpengine -> caller freeswitch -> robot
I see in a pcap that RTP packets goes from rtpengine to caller freeswitch
without significant jitter. But sometimes caller freeswitch make a ~200ms
length pause in RTP transmitting. After pause caller freeswitch renew
transmitting of RTP packets, and first packet have a marker bit set. As I
know from RFC 3551, marker bit means that stream starts after pause of
This pauses are very harmful for me becuse them break speech recognition
process of robot freeswitch side.
I use PCMA codec with ptime=20 and no any virtualization of caller
Do you have any thinks about reason of this pauses and how can I remove
With best regards
