Works great!!!

I frequently use the Vonage app and have had very good success with it. Most numbers called within the U.S. are free. Sound comes thru very clear.

The only thing Ive had issues with its that an incoming call on the phone itself will cause Vonage to go into the background and places the Vonage call on hold.
