Configure SPA3102

It looks tricky but believe me that it is very easy. The fruits of success will be tremendous.

Legend:

1. For the sake of illustration lets identify my Cellphone as 905Cell

2. Lets identify my home phone line as 905Home (in my case it is a Vonage line with a World Plan)

3. Lets identify my SIP based soft phone line as 905Soft 

Instructions

1. Connect a computer to the SPA3102 ethernet port just so you can access the admin web interface of SPA3102

2. Launch 192.168.0.1

3. Login as "user" with a blank password (I think.. if not then try "user" as the password also)

4. Lets change a couple of basic settings first

Navigate to Admin Login -> Advanced -> Router ->LAN Setup

Change "Auto Net Service ..." to 10.0.0.0-10.255.255.255,192.168.10.0-192.168.255.255,172.16.0.0-172.31.255.255
Change "LAN IP Address" to 192.168.10.1

(What you have done here is changed the embedded network router on SPA3102 to use a different range of IPs than your home network just so you don't have any conflicts. I don't use the router embedded on the SPA3102 and this does not matter much to me)

Navigate to Admin Login -> Advanced Voice -> System
Change the default password for "user" to whatever you like. A must do for security.

Save settings and Restart your router. Remember now that your router web admin is at 192.168.10.1 as changed above (assuming you are connected to the ethernet port of SPA3102) 

5. Lets configure SPA3102 so it can connect to the Softphone account 905Soft
Admin Login -> Advanced  ->Voice ->Line 1

Change values as shown:
Note:
In my case of a Vonage Soft Phone the User Id and password were available on the features page of my Vonage.com account online.

Change your line 1 dial plan as below

Note: plethora of info on dial plans is available via Google- suggested search "SPA3102 Dial Plan"

Note: [2-9]11! prevents 911 and other n11 numbers from being dialled. I actually had a family member accidentally dial 911 while they were using my Service!

6. Let's now configure the connection from SPA3102 to the Home Phone line 905Home (in my case Vonage with the World Plan)

Admin Login -> Advanced  ->Voice ->PSTN

7. Now lets work the magic so calls coming in on 905Soft will forward to 905Home

Admin Login -> Advanced  ->Voice -> User 1

  8. Finally: optionally, you can change the dial tone so that SPA3102 gives you a nice unique dial-tone versus a default tone that sounds like a busy tone. This is the tone someone calling into 905Soft will get. I actually wired in the Australian Dial Tone here in the field "Outside Dial Tone"

Admin Login -> Advanced  ->Voice -> Regional

 9. So what are you waiting for? Dial the number for 905Soft from your cellphone, hear the Australian dial-tone, then dial the number you want to call and you are all set! Remember that you can download a dialer like Dialer-X for your Android cellphone to automate this 2-step dialing.

Enjoy your personal GV!
