Deal Details

This is a new thread in the spirit of it's predecessors:

Googlevoice + Asterisk pbx (PiAF) + Free DID from SipGate = Free incoming/outgoing USA VOIP service

Google Voice + Sipgate + MySipSwitch - Asterisk = Free Inbound/outbound Calling No Server required

This is a new, simpler method using the newly released Asterisk 1.8. Most of the setup is automated by a package called The Incredible PBX by Ward Mundy who has also written a decent tutorial:

5 Steps to Paradise: It’s Incredible PBX for Asterisk 1.8 [nerdvittles.com]

I have tested this extensively and it works as advertised. I am able to make and receive calls using my home phone for free using a Google Voice number. I will be be writing a FAQ in this post and providing support to anyone with questions.

An important note:
You should really configure this with a Gmail/Google Voice account that is seldom used. If you are signed into Gmail using your browser and a phone call comes in, it will ring in your inbox instead of the home phone. To avoid this, register a new gmail account and then go to www.google.com/voice [google.com] and pick a number. Why not...both are free!

Someone else pointed out that if you stay signed out of chat while in your Gmail inbox, then you can use your existing account as it will not accept incoming calls.


FAQ:

1) What do I need?

* A computer to PBX-in-a-Flash, a Linux distribution pre-packaged with Asterisk. This can be a dedicated machine OR a virtual one. I have tested this VMWare Server and VirtualBox (both free!)
* An analog telephone adapter ($30) for using a regular phone OR a free software phone if can sit at your computer to make the calls.

2) This doesn't need Sipgate or Gizmo or another service?

No. The recently released Asterisk 1.8 has support for direct making and receiving calls using Google Voice without any other third party services. All you need to do is provide Asterisk with the user and password for the Gmail account.

3) How do I set this up?

Read Ward Mundy's tutorial:
5 Steps to Paradise: It’s Incredible PBX for Asterisk 1.8 [nerdvittles.com]

4) How do I configure the Linksys PAP2 for use with this PBX?

With the PAP2 at default settings, bring up it's web interface by typing the IP of the device into a web browser.
NOTE: To get the IP of the PAP2, pick up the phone and press * four times. When the man answers with "configuration menu" press 110# and he will read you the IP.

* Click Admin Login on the top right.
* Click Line 1 at the top
* Make sure Line 1 is enabled
* Proxy field should be the LAN ip of your PBX
* Register: Yes
* Display Name, User ID, and Auth ID should all be the asterisk extension you are connecting to. Mine all say 701.
* The password field needs the "secret" from the extension in FreePBX

New device call Obihai Obi110 which work with Google Voice without any other device.
- So don't need computer or server running Asterisk
- and don't need Linksys PAP2 since this device pretty much has all the features of Linksys PAP2
It replace both Asterisk and analog telephone adapter (No computer and OTHER device needed)

And you can get it from Amazon
http://obihai.com/how-to-get.html

Pretty good review of Obihai OBi110 VoIP device
http://michigantelephone.wordpres...ing-calls/

Obihai Obi110 http://www.amazon.com/gp/product/B0045RMEPI/
Based on this review, I assume everything can be done using the device without using the Obihai server.

http://voxilla.com/2011/01/24/how...-free-2512

Looks like Step 7 , (B), it indicate
particularly those accustomed to configuring Sipura/Cisco IP telephone devices — may feel most comfortable with this method. It uses the complete configuration tool that resides on the OBi110 itself.

Link to the OBi110 Device Administration Guide (pdf file)
http://obihai.com/docs/OBiDeviceAdminGuide.pdf

So the Google id and password should be store in the Obi110 itself.





Since some people are concerned about electricity costs, I did some research and ran the numbers:

http://www.newegg.com/Product/Pro...6856167037

Heres one nettop with a dual core 330 atom, one of the reviews measured power with kill-a-watt and says its 25 watts.

30 days * 24 hours = 720 hours in a month, * 25 watts used all day = 18 kwh used in a month.

At 11 cents per kwh thats under $2, under TWO bucks a month. Even if your electricity is more expensive the total is still not gonna be that much. You can't tell me you are able to buy any sort of PBX or cell phone or VOIP pay monthly plan for less than that Smilie
(not counting the free solutions, such as this one, or using a used wifi only cell phone)

Counterfeit ATA warning - The Linksys PAP2 is about $50 shipped at any reputable reseller. Those sold "new" on ebay for ~$30 shipped come from Hong Kong or China. Sound legit to you? If you're willing to risk a fake product, go for it. Otherwise, buy from Amazon or some other reputable retailer. Really? I got a 10-pack last year @ ~ $30/ea and did not have a problem.

So let me get this, you do not need a computer running to use GV number on a home phone?
How soon can you get simplified steps and hardware that needs to be purchased posted?

Reading all those old threads would be painful. I and others are likely to be more interested if you can simplify the steps.

Thanks in advance.

You will need a computer running in order for this to work. I have added this to the FAQ in my original post. The only other hardware you will need is an analog telephone adapter such as the Linksys PAP2 ($30, ebay).

This method differs from the previous ones in that it:

1) Does not require third party services such as Sipgate or Gizmo.
2) Is far less complicated to set up. Mine was "out of the box" working. I just had to give it my Gmail credentials and configure my PAP2 as an extension.
3) Is far more stable and reliable.

Now all we need is an app for android.

Then again, with this method you get a dial tone at home too, which is nice.
I might consider doing this on my router sometime.
(You can put asterisk on OpenWRT).

It's more complicated, but it means I won't need a computer running all the time.

Just get one of those hosted asterisk pbx, got mine for $15/mo from rentpbx, and avoid the hassle of keeping a server up 24/7. It is vps based and they got asterisk 1.8 ready to be deployed in just minutes. so far so good.

http://pbxinaflash.net/downloads/

Click on one of the mirrors. I used Google and got version 17553. Once you install PBXIAF it will ask you what version of Asterisk to use. Select Asterisk 1.8 and it will download the package and deploy it. As a result, an internet connection IS required during the install of PBXIAF.

pbxinaflash-17553.iso = 32bit
pbxinaflash-x86_64-17553.iso = 64bit

This thread is about The Incredible PBX by Ward Mundy. It is a package that configures this functionality automatically, so it is essentially working "out of the box". This automation is what makes this solution so attractive. Configuring this by hand using a hosted asterisk solution is not a viable solution for most people, myself included.

Correct. I have no experience configuring this on a vanilla asterisk 1.8 install. It looks to be fairly complicated.

Yes, if you have a computer lying around and don't mind keeping it running 24x7, sure, cheaper do it in house, but some people, like myself, tried in house, but too much hassle to maintain. At least, with this hosted pbx from rentpbx, you just select the package, and run the script incredible1.8. It's all preinstalled. same thing. no difference, just follow tutorial. just do not need hardware and iso to install.

And getting it running on router is just too much work, at least for me.

Not sure how other hosted pbx providers do it, but with rentpbx, when signup, just select piaf 1.7.5.5 purple. you'll get the server running in 15 min. Plus, they offer free 7 days money back guarantee if you want to try it out for free and for minimal work.

It was my understanding that RentPBX only offered vanilla asterisk but I now see that they also offer PBXIAF installs. Therefore, you are correct and this should work fine in a hosted environment. I must add, however, that I have not found that running my own PBX has required any kind of extreme maintenance. I have the server in a closet, plugged into power and network. I don't even have a keyboard mouse or monitor on it. I can't even remember the last time I needed to reboot it. Also, the $20/month for a hosted PBX kind of negates the whole "free" angle of this method. You can get bring your own device VOIP for far less than that.
