[Users] snom registration expiry

Mon Jan 9 10:49:39 CET 2006

Hi!

Looks like the SNOM phone has problems with the DNS resolving. If you 
compare the log of the phone, 5 minutes after the initial REGISTER. In 
case of sip.de.domain.cc everything is fine. In case of 
siptest1.domain.cc, the phone does DNS lookups, but does not reREGISTER.

Thus, I guess there is a problem with snom/DNS or with your DNS 
configuration. Try to swap the domains for ser and openser.

btw: are these the real domains (sip.de.domain.cc) or did you changed 
the logfiles? I can't find any SRV records for those domains.

regards
klaus
