Im trying to configure asterisk in order to use one sip extension of another external server as local voip trunk.
Yes, there are a phone company that supply a router that haver sip extensions integrated and i try to use one of them as voip trunk of my asterisk server. This router have for example the *104 extension with a username and password that i can put in a softone (as Zoiper), and works fine.
Well i create a voip trunk in my digium GUI and configure:
PROVIDER NAME: ROUTER
With this configuration i can receive incoming calls but can’t make outgoing calls.
When I try to make a call, the respones is a direct hangout.
I believe that not is problema of the outgoing plan because i have another configuration that use a FXO and i can make external calls.
Is possible use an external extension of another server as voip trunk?
Someone can say me how i have to configure the voip trunk?
