International Calls Fail in 3cx V. 3.1

[Ryandc]

Have a system that's working swimmingly with all local and long-distance calls here in the States, but I'm not able to make any international calls. The phone's dial plan is configured correctly for international calls. For whatever reason, I keep getting an error 480 on any attempted international calls. Logging, followed by additional details below:

CM104008] Call(1130): Call from Ext.225 to 011617559705XX terminated; cause: 480 Temporarily not available; from IP:192.168.0.1

Router: Edgewater Edgemarc 4500 (192.168.0.1)
Server: Win 2003 Server Standard (192.168.0.12)
Endpoint: Linksys SPA-922 running Firmware 5.15 (192.168.0.28)
VOIP Provider: Veracity communications w/ a 10-channel SIP trunk

I'm thinking the router is timing out the call prematurely, but I could be mistaken. Any thoughts?

You'll have to check with your VOIP provider. The 480 is a response from your provider that the number you want to dial is not 'available' for you to dial.....
