[Asterisk-Users] Problems with SIP Registration at PSTN Provider

Hi together,

I have a asterisk running on a Debian testing system running
"flawlessly" at least after starting the asterisk.
The Server its running on has a fixed IP, no NAT, whatsoever and is
reachable all the time. The Firewall has holes on port 5060 and for the
RTP-range that asterisk is configured on.

In my sip.conf I have a few register=>lines and I can receive calls over
those accounts.
However after a few hours, days whatsoever asterisk is still thinking
that those registrations are valid(CLI) but my provider (sipgate.de)
sees the asterisk as offline and hence does not forward calls to my
asterisk box. I tried playing with the *expirey values in the sip.conf
but I have no clue how to test it properly cause it can work fine for
days and then stop working ...
Sipgate is running SER btw.

Is that a known problem  ? Has anyone a solution other than restarting
asterisk every hour or so ?

regards,
