VOIP: It’s not as stable as POTS

Voice Over the Internet Telepnhony is growing, but companies using it should have backup solutions in place and know that when the power goes out their phone service could also. Not just power though, but as Vonage has experienced other problems – computer glitches – also.
Reuters writes Subscribers to telephone services over high-speed Internet connections provided by privately held Vonage suffered widespread outages across the United States on Monday due to a routing problem with network carrier Global Crossing, a Vonage spokeswoman said.
Edison, New Jersey-based Vonage, which has over 200,000 customer lines, told subscribers on their account Web pages the problem lasted for about 90 minutes and attributed the outage to an error in Global Crossing’s network that had data being routed to the wrong places.
