Also, the adapter can register to one provider (e.g., VOIPo) but still receive incoming calls directly from IPKall or G5 or another adapter. Some adapters and soft phones have a specific setting to support receiving calls without registering, whereas others don't. My point is that port forwarding is necessary to receive calls that go directly to the adapter.
I have two PAP2 adapters (one for VOIPo and one for NextAlarm), plus two old AzaCall/UTStarcom adapters from Lingo. I also sometimes use an XLite soft phone. Most of this is just for fooling around.
