Vonage dismisses hack warnings

Vonage has not responded to a warning about its voice over Internet Protocol (VOIP) vulnerabilities, reports NZ Herald.

Vonage is allegedly vulnerable to attacks by hackers who are able to intercept calls to the company`s subscribers.

VOIP security company Sipera Systems said it had informed Vonage of the problem more than a month ago, but the company has not responded to the warning.

Global Crossing has broadened the scope and reach of its VOIP services by extending to major cities in Mexico and in the United States, reports CNN Money.

The addition of Mexico brings to 21 the total number of countries worldwide where the service is offered.

In the US, the company expanded availability to nearly 400 additional cities, including Las Vegas, Salt Lake City, and Tucson, bringing that total to more than 1 400 nationwide.

Covad has announced that its Voice Optimised Access (VOA) service is now being used by over 50 service providers to deliver VOIP services to their customers, reports TMC Net.

Among these customers are the Communications Xchange, Thinking Phone Networks, and North American Telecom.

These providers offer voice services to both businesses and residential customers.
