I am looking for a first hand review of the Vonage WiFi phone (WiFi UTStarcom F1000). How does its quality compare with using a regular phone (with a Vonage phone adapter) on the Vonage network? I am NOT asking about traditional phone service vs. Vonage phone service (however this would be an interesting comparison). I AM asking about Vonage WiFi phone (WiFi UTStarcom F1000) vs. regular phone using a Vonage phone adapter. Links to first hand reviews will work as well.
