Yes, but ...

... you will need an additional piece of hardware to connect your
Vonage service to your Asterisk server because Vonage don't really
provide IP phone service. They only provide you with an analog phone
line. They deliver that analog phone line to you using VoIP
technology, but as far as you are concerned it is just an analog phone
line. So you will need some hardware to connect that analog phone line
to your Asterisk server.

If you have the converter box you get from Vonage in the same location
where you have your Asterisk server, then you could simply get an
additional FXO module for the TDM400 card and plug the Vonage line
into that.

Alternatively, you may want to sign up with a true VoIP service
provider in the US, for example Voicepulse Connect
http://connect.voicepulse.com which has various advantages over
Vonage:

- you don't need any additional hardware to connect to your service,
it's all IP.
- you get multiple concurrent connections instead of being limited to
a single line
- you don't pay any monthly rental for outbound services, only the
$7.99 for the DID number.
- you get IAX protocol support which is far superior to SIP in terms
of ease of use, security and reliability
