Asterisk & Portech GSM Gateway - Multiple VoIP Accounts?


I have a Pennytel “Talk Till You Drop” account (, and I’m thinking of purchasing a Portech MV-370 GSM Gateway to setup with this.

Basically, to make calls, I’d call the access number on the gateway, and be patched through. However, Pennytel offers both 38c untimed to Australian mobiles, or 10.5c a minute to mobile on a different plan?

Is it possible to setup the gateway/Asterisk to offer a choice between these two? How would you go about doing it?

Also, going the other way, is it possible to have my current SIM card in the gateway, so that when people call “me” (i.e. the gateway), it gets patched through to my mobile?
