A couple of years ago, I wrote a post about how to use a consolidated phone number for both the home and cellular phone. And while some degree of my method has changed in the couple of years, this method has been the same, and remained my way of having a home phone, and a cellular phone – while only needing to have one telephone number. However, in May of 2014 – Google will be terminating XMPP support with Google Voice. This will mean that most of the SIP providers, and IAX systems that plugs into Google Talk will no longer work. Now, companies such as Ooma, will still work – but this is because they just allow you to disclose your Google Voice number – but will use their network to make the call. You also have to pay $10/month + the ATA for this. Their ATA is about $150 – $200 which can be a little pricey when it means you will be able to plug a standard POTS phone into the device. You can also buy their cordless phones for better function – but these are $50 per phone, and the Ooma ATA only supports 4 phones. All together, you will be spending $500 + $120 per year for your home phone which may or may not do everything you would need to do.
I would still want a more unified solution, and while my proposed method will still be somewhat costly, it will be cheaper than the Ooma Solution. Keep in mind, there are a number of SIP providers that will allow you to spoof your CID to show your Google Voice number rather than a number they give you. As with the post this is replacing – I will use a similar format. I will go into detail on what you would need, then go into the hardware, and finally the services. I will identify how emergency calls are handled, and I will go into detail of what happens. I will go into additional options, and will explain what I “will” do. I will also go into the cost of services, and allow you to determine if the value is worth the investment.
