Hi,
we are facing the issue with automated failover in same SIP dialog in rtpengine
module. This issue occurs after we upgraded version 4.4.7 to 5.3.2 and only for
rtpengines that are in another datacenter with latency higher than about 100ms.
configuration
modparam("rtpengine", "rtpengine_sock", "1 == udp:10.0.0.1:2222
udp:10.0.0.2:2222")
modparam("rtpengine", "rtpengine_sock", "1 == udp:10.0.0.3:2222
udp:10.0.0.4:2222")

RESPONSE

Only possible fix is to have only one setid with only one server.
First RTPengine is not marked as failed in list of rtpengine servers after the
first response.
