[Freeswitch-users] Problem with rtp streams and stair-stepped (or ramped) increased lag

[Nathan Neulinger]

Having some occasional user reports of problem calls where they are fine, and then something happens on the call and lag 
increases significantly, sometimes up to 2+ seconds.

I've got severe examples on both cisco and polycom phones. What I'm seeing looks like the call is going perfectly for a 
period of time (sometimes up to a few minutes), and then there is a period of time with higher latency packets, and the 
overall delay in the graph increases steadily at that point, and never recovers.

It sounded like rtp-autoflush-during-bridge might be something relevant, but that's set to the default. Also saw 
"rtp-rewrite-timestamps", but unclear if that is necessary here.

I've got pcap captures of the rtp streams if that'll help any.
