This instance is running v1.2stable as of a week or so ago. (In a pilot, so trying not to update it very frequently, but when I add stuff to the skinny code.)
The interesting thing is - on MOST calls, it's working fine, and even on the calls that are a problem, it works fine, up until "something" happens, and then it starts building up the delay.
Even on non-problem calls, I occasionally see a slow/occasional stairstep that doesn't accumulate much, but on the BAD calls it accumulates to high delays.

I've seen a similar issue on a small network behind a pfsense router. Network diagram is: Hard Phones(3+ Yealink and Polycom mix) -> switch -> PFsense -> Comcast -> FS conferencing server.
In my case I was seeing ~10 seconds of RTP delay(tested from doing a/b response testing), but instant sip handling. The audio was in perfect sync coming from the conference server to the 3 endpoints.
Nathan, what version of FS are you running?
I have not yet ruled out that the issue isn't a local network problem.

In one particular stream, which is call mgr <-> FS, the CCM to freeswitch side of the stream shows no issues, but freeswitch to CCM direction shows a number of drifts, some just one ptime worth, others larger.
This instance is running as a VM, but allocated significantly more reserved cpu (and very high shares) on a lightly loaded host. Concurrent calls on the FS instance is in the single digits at most at this point. Typical end to end network induced latencies less than 3 ms at most.
Any suggestions on what to look at or steps to take here? Certainly not happening on every call, but I do believe I've seen it on both cisco and polycom phone connections. Usually, there is just a slow stairstep over the period of the call.

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.
