Just installed Asterisk, I receive but I cannot call

Hi, I just installed Asterisk, two IP phones, one SIP account on a local provider.

I created one new inbound route, I receive phone calls.

I edited the “default-out-route” to use my SIP account, but i hear “Your call can not be completed…”

What can I do ?
Dialplan ?

I don’t want to use prepends…

I solved… (adding XXXXXXXX…) in the match pattern.

I must to read the guide…

Can someone link me a simple guide to dial patterns ?

Have a look here: voip-info.org/wiki/view/Aste … n+Patterns. Voip-info is always a useful source of Asterisk information.
