[OpenSIPS-Users] snom m3 unable to reconnect to the OpenSIPS server

[Petr Man]

Hello list,
I have asked on the Snom forum about my problem with m3 phone in
conjunction with the OpenSIPS server a few weeks ago without any
helpful hints, where the problem might be. The original message is
here http://forum.snom.com/index.php?showtopic=1944.
My internet connection is an ADSL with regular interrupts every 24
hours (to prevent/make harder to have i.e. webhosting on you home
connection...). The router receives a different IP every time. After
the reconnection all the accounts configured on my phone successfully
register, except for the OpenSIPS server I am running myself. The
server has a static IP and is located somewhere in a collocation. When
I used a softphone and forced the router to get a new public IP, the
softphone didn't have a problem re-registering with the server.
Reseting the phone helps.
I suspect this is a firmware bug in the m3, but maybe someone has an
idea how to fix this, because the problem appears only with OpenSIPS.
The log from the phone is not helpful at all it shows a bunch of
register requests, but no answer. I haven't found any register
requests in the OpenSIPS log from that particular phone in the debug
mode, but I might have overlooked them. What should I put to the
config file to isolate the request I am looking for?
Cheers,
Petr
