Despite a Nov. 28 deadline, more than 30 VoIP providers have not met U.S. Federal Communications Commission (FCC) requirements to offer an emergency dialing service called enhanced 911.

An estimated 750,000 U.S. VoIP customers did not have enhanced 911, or E-911, service as of Nov. 28, according to the VON Coalition, a VoIP trade group.

The FCC had softened a requirement it adopted in May for VoIP providers to cut off service to customers who could not receive E-911. But the FCC, in a Nov. 7 memo, told VoIP providers the agency expected them to stop marketing in areas where they could not provide E-911 after Nov. 28.

E-911 service pinpoints the street address of a 911 call coming into an emergency dispatch center.

The FCC was still processing waiver requests from VoIP providers Tuesday, but more than 30 VoIP providers have filed requests for extensions, an FCC spokesman said. In October, VoIP provider Nuvio filed a court challenge to the Nov. 28 deadline.

SunRocket, a VoIP provider based in Virginia, reported that about 96% of its customers had E-911 service as of Nov. 28. The company reportedly has more than 50,000 customers.

Vonage, the largest U.S. provider of residential VoIP, said in a Nov. 28 waiver request that 26% of its customers had E-911 service available. Vonage announced its one millionth customer in early September.

AT&T also told the FCC that about 35% of about 57,000 CallVantage VoIP customers do not have full E-911 service.

About 90% of Vonage's customers have connections that support E-911, but many dispatch centers, using 911 services from traditional wireline carriers, are not ready to receive VoIP E911 calls, said Brooke Schulz, Vonage's senior vice president of corporate communications.

Vonage has undertaken "painstaking efforts" to meet the FCC's goal, with 125 employees working on E911 issues since June, the company told the FCC. But compliance has been slowed by some technical problems, including problems with number identification technology, as well as a lack of cooperation from some incumbent telephone providers and dispatch centers, Vonage said.

Vonage shares FCC concerns that a number of VoIP customers do not have E-911 service, Schulz said. "We've been working very hard and very fast," she said. "We've done everything in our power -- we've turned up every single element we can control and can purchase."
