Maybe I'm missing something, but are sipphone.com and Gizmo the same thing? If this is the case, then I understand what you mean about the settings being on rtcomm's site. I tried the settings that were listed under that section, to no avail. If they aren't the same, I didn't see Gizmo mentioned anywhere at all on the rtcomm site.

I have read just about everything that I can find on both ITT and in rtcomm's garage site, and can't quite get this going. Any assistance would be appreciated.

I am also attempting to get Truphone to work with the now integrated SIP service. I saw a post on another site alleging that this was possible, but haven't been able to find it again. Again, any direction would be appreciated.
