Hi all, I'm having this weird issue that I can't explain. Maybe someone can explain what is happening. This is a Asterisk install that has been in production for 6+ months. It's version 1.2.10. Couple weeks ago one SIP peer started disappearing randomly. And I mean it simply disappears. One second "sip show peers" shows it, and then it's gone. A simple "sip reload" fixes it: (all good...)

Sometimes it disappears after a few hours, sometimes after a week. The box can be mostly idle or loaded. No difference. I did restart Asterisk completely, no help. Upgrading is an option, but so far there was not need. Any ideas what is happening?! This peer has been fine for months, and now this. Line 2 on the Sipura registers with another box (it's actually Asterisk 1.2.5) -- no problems there. And yes, I did reboot the Sipura. --Luki
