Vonage and Asterisk

Hi Everyone,

I am looking for a solution that would connect my vonage line to a land line and I wanted to pick your brain on how to accomplish this.

What I want to do is to use my land line to call home and then get a dial tone from my Vonage line to do some international calls. Basically I need Asterisk to bridge my landline to the vonage line if I for example press “*#*pwd#” after I connect to Asterisk and drop to the Voice mail system using the landline.

I need advices on HW (Can I connect to Vonage directly from Asterisk? or I have to use the router Vonage provided and connect to that via analog line?)

Can this be done? Is anyone else doing this? Is there a walkthrough for an application like this? Did I ask enough questions? :stuck_out_tongue:


I’m new to Asterisk myself, but I did find (and can’t remember where now, I’m sure I googled a LOT to get it) some information that said you have to sign up for a Vonage softphone account in order to use the account with Asterisk. As for the rest…you’d need someone far more experienced than me, but I’d bet it can be done.

Well, Yes and no. You can go either two routes

1.) Purchase a Vonage softphone account (Vonage will give you the SIP
credentials) and configure your Asterisk server to connect to

2.) Purchase a VOIP adapter such as the SPA3000 and connect your
vonage PAP2/Adapter to the SPA3000. (This will allow you to connect
your locked Vonage service to your asterisk server and treat it like
a PSTN line).

From there all you need to do is configure your PSTN to fall over to
your VOIP (Vonage) line, and enable DISA to authenticate you by adding
something like this to your dialplan.

exten => 3,1,Authenticate(3670)
exten => 3,2,Background(pls-wait-connect-call)
exten => 3,3,DISA(no-password|from-internal)

Personally I add this to my Auto Attendant (option 3) off the main
menu. This will automatically fall over to your unused Vonage
trunk if your are dialed in to your PSTN line.
