[Asterisk-Users] Sip reg problem

[John Hill]

I get this error message in my syslog.
I have searched the list but I can't seem to find a answer that solves the
problem.

chan_sip.c: Registration from '<sip:2238 at 192.168.100.1;user=phone>' failed
for '192.168.100.2'


The asterisk server is running dev head. The server is the 100.1 ip. I have
3 ata186's numbered 110.2-4.

In sip.conf
I have 6 entries all the same except for the ip and extension number.
Username=2238 [-2243] 
Password=xxxxxxxx
host=dynamic
default ip=192.168.100.2 [-4] (2 phones at each ip)
Etc.

It works fine calls in and out. What am I missing?

Thanks
