Phones fail to register

Miguel Costa

Recommended Posts

I had a Windows 2003 server provisioned by a hosting provider (Rackforce).


The newest version of pbxnsip installed - and the interface is working fine. I currently manage a similar installation internally - but moving to a hosted scenario.

Anyways long story short, the phones can't register. Turned off the firewall, I can access the admin page and such - but the phones for some reason fail to register. Any ideas?

Can you see the REGISTER packets in the log of the PBX (turn SIP logging and and enable REGISTER messages; set log level to 7). If yes than the Firewall sends the packets to the PBX, step #1 is okay.


Then maybe check the Windows firewall for it's policy about letting the PBX access the network. Maybe it blocks outgoing UDP traffic. If you have a phone that has a logging feature for the SIP traffic, you can see if the 200 Ok to the REGISTER actually makes it to the phone.
