Hi folks, new forum user here. Previously had a 7200/7100 configured for SPNET and extension dialing between remote systems working fine for years. Recently had to switch the 7100 to a 7200 for more space and redo the programming. Now SPNET is not working between locations. I have tried my best to get all the settings correct, however when I attempt to dial a remote extension I get Invalid Number displayed.

Is there a specific setup manual for SPNET outside of the normal administrator guide that is available online? The setup is private IP over VPN and the tunnel is good as I can ping and connect to the remote 7200 with device manager. I'm pretty new to phone system programming as well so please be kind.

Getting closer, now it works one way but not the other. Do you have to power cycle the system if you add SystemLink ID or change IP in the SystemLink Table?

You don't need to power cycle.

Invalid number means the digits you are sending to the other system don't match an entry in the did table.

Thanks, nameless. That was the missing piece! Works like a charm now.
