Merctor Capital's most recent newsletter has inght about Vonage and their current and future offerings.
It's a good read and worth looking through. While not "news" per se, the author presents a good summary of Vonages plans. The reference to UK and Switzerland is interesting because Vonage has not said much on the subject of International, other than they plan to be International. Perhaps something was revealed to the author in a briefing.
That point deserves more understanding, but Vonage PR has been mum on the subject when I've posed the question before. Hopefully, this report opens up the log jam.
