Vonage asked the FCC for another extension to satisfy the agency’s rule banning fake ringing tones. “Due to the inability to leverage its existing system to meet the requirements of the Rule, Vonage is building a new system to play a message to customers in situations where a ring is not received from an intermediate carrier,” Vonage said in a petition filed Friday (http://bit.ly/1bGLar5). The FCC had granted Vonage’s initial waiver request by extending the rule to March 3; Vonage needs until April 2 to comply, it said.
