Hi, I have this weird problem i cant explain. i have two asterisk, i'm using realtime table for my sip/user accounts. my database is on a mysql cluster. my prob is if i register on phone on asterisk 1 it is ok, but on second asterisk it can't, Registration from '"122144" <sip:122144 at 10.10.10.131:5060>' failed for '12.34.56.78' - Wrong password but both asterisk talks to a single mysql cluster. i defined this on my sip.conf domain=10.10.10.130 domain=10.10.10.131 domain=my.domain.com any ides? TIA Regards, Ron
