SBC had been known to be working with VoIP carrier Vonage on E911, but reportedly the two have been dickering over technical and business details. Speculation is that SBC didn't want to announce E911 services until it had resolved the issues with Vonage, but recent events have overtaken the carrier.
Last week BellSouth said that it would provide E911 service to VoIP providers. That announcement came shortly after Vonage announced it had cut an E911 pact with Verizon (Initial reports in TelecomWeb had indicated that Verizon was providing E911 only to Vonage, but Verizon has since informed us that the offer is open to all VoIP carriers). Qwest, too, has acknowledged tests with Vonage and reportedly agreed to provide E911 to all providers.
