Odd disconnect?

[dswartz]

I doubt it too, since NAT isn't involved for me. I will be making a 30+ minute call tomorrow, so I will fire up a sniffer first.

Update: I tried calling my cellphone from the voipo number and after 30:16, it disconnected. Looking at ethereal trace now...

Update2: I don't see the update request either, and can confirm a BYE sent from the other end around 1800 seconds into the call. Bad news: asterisk 1.4 (what I am running) does NOT support RFC-4028. Possibly good news: asterisk 1.6 does (and that is much more stable now, as well as being (mostly) supported by freepbx 2.5. I will give a try to 1.6 and report back.
