Which means we caught you red-handed! Remember when I asked you about
whether you were using the default configs from the new firmware package?

That tells me right there that you didn't use the default sip.cfg and
phone1.cfg files.

I have learned the hard way that using old configs with new firmware is
asking for trouble. It is much better to keep your custom configurations
in a MAC specific overrides file and replace the sip.cfg and phone1.cfg
files completely.

This doesn't guarantee that you won't have problems, but it's a lot
easier to troubleshoot an overrides file with a dozen items in it than
to sift through big, customized sip.cfg files.

Well, you shouldn't need to re-register every 30 seconds, either. What
was the reason for configuring your phones like that?
