Simple Registration of Phone INCOM 1000 Help

Hello, I just picked up an INCOM 1000 wireless wifi phone. I have seen some admins with experience connecting these phones to a FreePBX system on here. I was wondering if someone could tell me where to put the server IP, ext. password to register this phone with the PBX. This should be an easy thing, but I cant figure it out. Thanks for the help.
