Any advice on porting landline to Sip providers, like you can do with Callcentric. I can't do to Google Voice because they don't serve my local area number. I am ok paying the fee to Callcentric (for occasional incoming, but will mostly use GV for in and out), but wonder if there are other options, and if all will charge you for e911 even if you have Anveo set up on Obi100 with GV. Simply, are there other Sip services like Callcentric that can be 'easily' configured with Obi100. Suggestions and Guidance appreciated. Rick
