Free VoIP phone service – OBi110 + Google Voice

FREE telephone service!*    FREE phone number!*   Tons of features!

The OBi phone adapter and Google Voice can be combined to create a great free* VoIP home phone service with a lot of features.  The system easily surpasses Vonage and Comcast VoIP offerings.  It takes some technical skills to set up and the future of the service is a little cloudy – Google may yank support of the OBi and start charging for Google Voice.  But those clouds aside, the service is working very well for me.

*Google has made Google Voice tm service free for 2012.  The OBi phone adapters are $44 and $50  at Amazon.  Broadband Internet service required.  Google Voice tm.

The two pieces that make this work are Google Voice and the OBi phone adapter.  Google Voice is a feature rich telephone service.  Google Voice includes a free telephone number (US only),  free* local and US long distance, voice mail, voice mail transcription, SMS texting and flexible incoming call routing.  The missing piece for Google Voice to be a complete home VoIP service was an easy way to make and receive telephone calls from your home phone.  Presently you make and receive calls from your PC or you must have phone service (landline or cell) to receive incoming calls or call first to Google Voice then call out to your destination.  The OBi phone adapter is the missing piece – the OBi allows placing and receiving phone calls with the home phone.

My setup – Google Voice, OBi110 and iPhone

I have a Google Voice number, an OBi110 phone adapter, cordless phone and an iPhone.

I have it set up so incoming calls to my Google Voice number simultaneously ring my home phone and my iPhone.  I can answer either device.  Unanswered calls go to Google Voicemail.

Calling my cell number only rings my cell phone.  Unanswered cell calls go to Google Voicemail.

Google Voicemail is transcribed (voice to text) and the transcription is texted to my cell phone and emailed to my Gmail account.  The email also contains a link to the voice message.

My old landline (a magicJack Plus) is plugged into the OBi110 so calls to that old number ring on the home phone.  Unanswered calls go to magicJack voice mail and notice is emailed to my Gmail account.
