Analog call through SIP

Hello,

Is it possible with Asterisk to have :

someone call the Asterisk server on the Analog line (from landline or mobile), and from here can make a call to antoher landline but via SIP ?

I have the following :

mobile (user1) — Asterisk — Internet ---- VOIP SIP server ---- analog line — user2

The Asterisk server and SIP server are in different countries, to reduce the costs, I would like to be able to make a call to my Asterisk server, then enter the number of the landline I want to call, and Asterisk will make this call via SIP.

Is this possible and if so … how to do this ?

Many thanks

Yes. Have a look at the DISA command:
