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@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 --john
