Poor Vonage. It has been a bad few years for them. They've been shoveling out money left and right to companies like Sprint and Verizon. They've been plagued with security woes. All of this and more has led to the company having difficulty staying afloat.
Despite all their troubles, they are still manage to increase in value, probably since the liability of owning a piece of Vonage is going down. That said, they are still $16 million behind and the amount of cancellations has been increasing, primarily due to customer service issues.
It would be a shame to see one of the pioneers of VoIP be crushed, so I hope they manage to fully recover.
