I just installed FS on a fresh Centos 5.3 install, everything went perfect. I loaded x0lite up on a couple of hosts and they registered and worked fine. Then I moved the Centos server to a new subnet on out network that we have tons of boxes on and have all the routes already configured on and now the Sip phones will no longer register. No other changes have been made on the FreeSwitch server other than changing the IP. BTW I can ping to and from the FS server and the hosts and the firewall is off on the FS server and the hosts. I plugged a laptop with X-lite into a switch on the same network so the packets don't even need to route and it still won't register! BTW I also downloaded 3CX VoIP phone and it behaves the same way. Any ideas? TIA =-=-=-=-=-=-=-=-=-=-=-=-=-=-= EDCO Group, Inc.
