By Paul Kapustka - Advanced IP Pipeline Vonage Holdings Corp. said it is investigating new potential incident of its Voice over IP service being blocked, this time by a cable television company that also provides Internet services.
Brooke Schulz, Vonage's vice president for corporate communications, confirmed that the company is "investigating a new instance" of service interruption that appears to be another case of port blocking. Schulz said the incident involves Vonage customers who use high-speed Internet services provided by a cable operator, somewhere in the Midwest U.S.
