Would this phone work with vonage?
Yes. It is essentially a Dual-Phone. It is designed to work with Skype and directly plugs into your highspeed Internet Router (no PC needed). As a Dual-Phone, it is designed to also plug into household PSTN telephone jacks. This way you can switch between Skype and PSTN calls. In the case of people using VoIP adapters like Vonage, the Skype phone PSTN phone jack will plug directly into the Vonage adapter phone jack. So, now you should be able to switch between Skype calls and Vonage calls. This phone should also work with any VoIP adapter that has an RJ-11 phone jack connector. So, instead of plugging in a regular phone to the adapter, just substitute the Skype Phone RJ-11 connector and again it will work as a dual-phone.
