Hi There!
I have signed up for onenumber which as I understand it allows me to load sipdroid on my android phone and it means that if someone rings my number, both my home phone (Connected via ATA) and my Android Phone will ring. In order to do this I need to change my authorization username to my number and then a -1 so 5559999-1
The problem is that no matter what I try I can't make it work. Won't register/authenticate if I use that Number.
