Wireless Fixed Terminal CDMA phone installation with *

Hi. I don’t know if it’s the right place but I’m an old newbie already. I have a project in line for a PBX box in my 2 houses differently located. My hardware includes a WFT(WIreless Fixed Terminal) CDMA phone which I used before a a dialup connection to the Internet here in the Philippines and an Ubuntu 10.04 server. Is there a way to configure my WFT CDMA phone to work with Asterisk to connect my PSTN phone in a nearby province? I will be using an ATA phone adapter to the province via Internet to connect my asterisk. Any good suggestion is much welcome.

Thanks and Regards,
