Folks: This is my first post, so please let me know if I transgress in any way... In updating to 1.4.21 recently, we've encountered a problem, when running over a satellite connection (where the latency is considerable; a "regular" internet connection did not exhibit this problem), where incoming calls are being dropped as a result of the sip handshake timing out (dropping down to 1.4.18.1 solved the problem for us). From reading the change logs and other posts, it seems that some work has been done in this area recently to get it "right"; it appears that, at least in the satellite case, things may have gotten a little too "tight"... If this rings a bell for anyone, any insight would be appreciated. Many thanks, --ag -- Artie Gold F4W, Inc. -------------- next part -------------- An HTML attachment was scrubbed...

It also helps when someone else is searching the mailing list archives.

This value is settable globally, as well as per-peer. -- Tilghman
