"I have an AT&T number ported to Google Voice. There isn't any service out there that thinks it's a VOIP number." This 'lookup' script that I wrote will properly identify your number as being owned by google voice: /usr/local/bin/curl -s -X GET "https://lookups.twilio.com/v1/PhoneNumbers/$number?Type=carrier&Type=caller-name" -u $accountsid:$authtoken | /usr/local/bin/jq '.' ... given any phone number, I can see, using the twilio API, where the number currently terminates to and who "owns" it - including subscriber name (ie., your name). I'm glad it continues to work for you because it should and you should be able to use a gvoice number in this fashion but ... you've just gotten lucky so far.
