Make free calls with Google Voice, Gizmo5, Sipsorcery and ATA Devices

I will show you how to make free calls using Google Voice, Gizmo5, Sipsorcery and ATA (Analog Telephone Adapter) device. If you do not have a Gizmo5 account, then save this blog in your favorites until you do. Since Google acquired Gizmo5 back in November, signup has been suspended until further notice. You will also need a Google Voice number. If you don’t have one, request an invite here. Or request one here as I have a few left to give out. You will also need to signup for an account at Sipsorcery. Here I will use the Cisco ATA 186 adapter. You can, of course, use other SIP devices like the more popular Linksys PAP2T-NA which is cheaper.

From here on, I will assume you have all four requirements above.

1. Adding your Gizmo number to Google Voice account

Before adding your Gizmo number to Google Voice, you need to install the Gizmo softphone. You will need this softphone to verify your number.

Log on to your Google Voice account, go to "Settings" and click on "Add another phone".



Name : Give it anything you like
Number: Your Gizmo number
Phone Type: Make sure you select Gizmo
------------------------------------------------------------------------------------

Once you click on "Save", you will see a popup window with the verification code.



With your Gizmo softphone running, click "Connect" on the popup window and it will call your Gizmo number. Answer the call on your Gizmo softphone and enter in the verification code when prompt.

2. Configure SIP Sorcery account

Log on to your SIP Sorcery account

Click on the "SIP Providers" link at the top left corner, then click on "Add" under the SIP Providers section

Provider Name: Anything you want
Username: Your Gizmo number
Password: Your Gizmo account password
Server: SIP:proxy01.sipphone.com
Register: Checked
Register Contact: SIP:sipsorcery username@sipsorcery.com
------------------------------------------------------------------------------------

Click on "Update" will add/save your SIP provider info.

Click on the "Dial Plans" link and then either edit the "Default" plan or add a new dial plan. Here, I selected the default plan and pasted in the dial plan I copied from Norske & EasternPA. Here they also show you how to set this up with the Linksys PAP2T-NA ATA to work with Sipgate and Gizmo5.



Dial Plan Name: name it anything you like
Script Type: Ruby
------------------------------------------------------------------------------------

Copy and paste the dial plan script from Norske.
Change the "Area=" to your area code and the "Tz=" to your timezone.
The other things you need to edit from the script are the line under "GoogleVoice" section: sys.GoogleVoiceCall('GV username@gmail.com','GV password','1747#######',@num,'.*',7)

GV username: Your Google Voice account name
GV password: Your password
#######: The rest of your Gizmo number
------------------------------------------------------------------------------------

In the script, you can add speed dial numbers among other things but I will not go into details here, refer to the article link above. Click on "Update" to save your dial plans.

**Notice that your Google Voice account password is in plain text and if you think you'll lose sleep over this, then I suggest you create a new Gmail account and request Google to transfer your GV number over to it. This way your main email account is not exposed to hackers. Here is the link to request the number transfer. It took Google one day to transfer my number. Yes, I was losing sleep over this. :)

Request to allow Google Voice account transfer

After creating your dial plans, click on "SIP Accounts" link and then click on "Add" and enter in your SIP Sorcery account info.



Username: Your SIP Sorcery username
Password: Your password
Out Dial Plan: Click the drop down box and select the plan you created
In Dial Plan: Leave it blank
Keep Alives: Checked
Network ID: Leave it blank
IP Address ACL: Leave it blank
------------------------------------------------------------------------------------

3. Configure your Cisco ATA device to make and receive calls on cordless phone

If you are connecting your ATA to the network for the first time, follow the instructions below. The instructions is taken from the Cisco ATA administrator guides.

Using the Voice Configuration Menu

To manually configure the Cisco ATA by using the voice configuration menu and the telephone keypad, perform the following steps:

Procedure

Step 1. Connect an analog touch-tone phone to the port labeled Phone 1 on the back of the Cisco ATA.

Step 2. Lift the handset and press the function button located on the top of the Cisco ATA. You should receive the initial voice configuration menu voice prompt.

Step 3. Using the telephone keypad, enter the voice menu code for the parameter that you want to configure or the command that you want to execute, then press #. For a list of voice menu codes, see Appendix B, “Voice Menu Codes” in the administrator guides.

Table 3-6 lists the menu options that you need to configure basic IP connectivity for the Cisco ATA, after which you can use the Cisco ATA web configuration page to configure additional parameters.

Note If you are using the voice configuration menu to statically configure the Cisco ATA IP address, you must disable DHCP by setting its value to 0

Table 3.6
-----------------------------------------------------------------------------------
Cisco ATA Voice Menu Number Features
1 StaticIP—IP address of the Cisco ATA.
2 StaticRoute—Default gateway for the Cisco ATA to use.
10 StaticNetMask—Subnet mask of the Cisco ATA.
20 DHCP—Set value to 0 to disable the use of a DHCP server; set value to 1 to
enable DHCP.
21 Review the IP address of the Cisco ATA.
22 Review the default router for the Cisco ATA to use.
23 Review subnet mask of the Cisco ATA
-----------------------------------------------------------------------------------

Step 4. Follow the voice prompts and enter the appropriate values, then press the # key.
Note Use the * key to indicate a delimiter (dot). For example, to enter an IP address of 192.168.3.1, you would enter 192*168*3*1 on your telephone keypad.

If you have one sitting on the shelf collecting dust and don't remember the password, you can reset your Cisco ATA to factory default values. To perform a factory reset, you must use the voice configuration menu and follow these steps:

Procedure
--------------------------------------------------------------------------------
Step 1 Press the function button on the Cisco ATA.

Step 2 Press the digits 322873738 (FACTRESET) then press # on your telephone keypad.

Step 3 Press * on your telephone keypad to confirm that you want to reset the Cisco ATA, then hang up the phone.
--------------------------------------------------------------------------------

Once you have your network values set, you can access the configuration menu through your web browser. The IP address of my ATA is 192.168.1.103. I type in the browser URL, http://192.168.1.103/dev to access the ATA configuration menu.



The parameters you need to enter are:

UID0: SIP Sorcery Username
PWD0: SIP Sorcery Password
GkOrProxy: sipsorcery.com
SIPRegOn: 1
SIPPort: 5060 (**Need to open this port)
OutBoundProxy: sipsorcery.com
MediaPort: 16384 (**Need to open this port)
NatServer: stun01.sipphone.com:3478
------------------------------------------------------------------------------------

Click on "Apply" at the bottom and then click on "[Click here to reload]" link at the top.

Log on to your SIP Sorcery account and check to make sure your SIP account binds to your Cisco ATA device and your SIP provider binds to Gizmo successfully. If they are, pick up your phone and you should hear dial tone.

To dial out, you can either dial 1-(area code)-number-# or just (area code)-number-#.

If you have problems dialing (fast busy or one way audio), make sure you have ports 5060 and 16384 open to your ATA device. Instructions on how to forward ports can be found here.

Happy Dialing!!!
