Can you describe your setup? Need to know what kind of OS and hardware is running FS as well as what kind of phones. Any NAT involved? -MC
FS is running inside pfsense, which is a freeBSD-based firewall (pfsense.org). Hardware is a lightly loaded Soekris net5501 (500 MHz Geode x86, 512 MB RAM)(www.soekris.com).
FS external and internal profiles are both listening on WAN with a public IP address. My extensions are 2 lines on a Linksys PAP2T residing on the LAN, registered to the internal profile on the WAN interface. All calls are made via a sip trunk.
PAP2T normally reports a decode latency in the neighborhood of 30 ms and jitter of 5 ms. Ping time to my provider's rtp servers is ~42 ms.
Every call starts out with imperceptible latency, but at some point the caller notices a long delay, as I said, usually around 3 seconds, and usually only on calls lasting 500 seconds or more.
Anything else I can provide?
Hmm... Might want to ask Mark Crane (IRC: mcrane) if he's seen anything like this with FS+pfSense. The FS devs aren't exactly keen on FS + FBSD because of some issues between a FS dependency (APR) and the FBSD threading model. Still, on a light load I wouldn't expect this kind of behavior. -MC
