No. Vonage phone service utilizes your Internet service connection only, not the computer. The only time you may need your computer for the Vonage service is if you use something like the Vonage SoftPhone®.
Vonage SoftPhone is a fully functioning VoIP telephone interface that you can download and install on your PC or Mac and use without your Vonage phone adapter, even when you are traveling. With the SoftPhone you can make and receive calls, pick up voicemail and use most other Vonage features.
