It's all set up and I'm very happy today.
I'm just posting in the forum to put in what I did and how it went.
Tuesday I ported my house landline to T-Mobile as outlined here:
http://www.obihai.com/porttutorialI used that tutorial as a reference the whole way.
T-mobile SIM card was $7 on amazon.
T-mobile required minutes for the pay as you go phone, $10 minimum.
The SIM card was active and working by Wednesday.
You need an unlocked cell phone , then, to port your number to google voice as google voice calls that number you're trying to port to google voice and expects a confirmation code to be typed in on the live line while your doing stuff in google voice on your computer. $20 for that. Make sure to do this through Google Voice Legacy from the settings of the new Google voice UI.
Worked great. Google voice had a hold of my ported number within 24 hours.
Friday night I set up the Obi account, added the google voice account and after it authenticated it was taking a long time to connect to the IP address.
I set my router to pick the DNS server automatically rather than my DNS server numbers for Open DNS. It connected instantly, then.
The phone tested out great, I called out, called in. All's good.
I reset the DNS servers back to open DNS and the phone is still fine in and outgoing.
House-wise, I found the mainline feeding my phone box for all the phones in my house (no wireless; 4 corded phones and a fax machine) and connected that wire to a newly purchase phone connection box to which I plugged in my ObiHai200 into that. All the phone lines are connected and working, no outside service lines are attached to that circuit at all.
I'm a happy Obi user now.
All in all, $30'ish for the ObiHai200 , $17 for T-Mobile, $20 for google, $8 for misc phone line stuff.
All set,
Thanks to this forum and it's info.
