I had an OBI-100 that's worked for years and then my cat urinated on it and the lights went out and can't connect to the network.
So I bought an OBI-200 to replace it.
I had it connected to my PIAF PBX, but now when I connect the OBI-200 and try to dial out, I get a recording that says exactly what the Subject says:
The number you dialed... was rejected by the service provider. Reason is 603.
The status on the dashboard says that it's Registered. Pretty much everything is exactly the same.
I can connect to the PBX from a softphone and dial out normally.
Any suggestions on why the OBI-200 is giving me the 603 error?
