Asterisk with GSM network


Can anybody help me with the required configurations needed to route a call from an extension connected to
an Asterisk server to an external number from a GSM network?
Thank you in advance

You mean to call a cell phone from your Asterisk extension?

… or do you mean connect Asterisk to your cell phone and call out through that?

… or do you mean add a GSM Interface and connect a trunk to a cell phone number?

Clearly we need more to help you.


I am trying to call from an extension defined on the asterisk server to a cell phone number.

You need to setup an account with a sip trunk provider.
