[asterisk-users] Asterisk+Sipura 3102+PSTN line

Hello Gurus

I've installed my Asterisk server for testing on the company I work the setup or the approach let's call it is:

1 Asterisk Server fully configured and with some SIP extensions setup on two cities A and B.
2. One local PSTN line connected thru a x01p card to call local phone numbers numbres on city A.
3. A Sipura 3102 Gateway on city B connected to a city's B PSTN line.

I wnat to be able to call from city A to city B PSTN phone numbers from city A using Internet and vice-versa. What is the proper config on Asterisk and the SPA-3102 so that I can call SIP extension on that device plus PSTN phone lines.

Thanks for the tips or the pages/guides I can be referred to.

Thanks! :)
