I know this is off topic, but I suspect this list may have someone who can explain a recent VoIP experience, or perhaps provide a vector to someone who can.

I have a single public IP from my ISP with a single router. Connected at the time were my Allstar nodes, Win7 PC, iPad Air, and VoIP phone (Ooma).

I called my sister on her iPhone using my VoIP (Ooma) connection. She did a dial back based on my call to the VoIP number. The VoIP connection did not respond, but my iPad Air did, and we were both instantly in a Facetime chat, but without video.

We are mystified by this experience; how her call got routed to my iPad Air (not to my phone connected to the VoIP box), and how the Facetime app was selected on both Apple devices.

Thanks,

Bob
