[asterisk-users] SIP peer disappearing

[Luki]

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...)

It only affects one peer. 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.
