LAS VEGAS -- MetaSwitch and Calix announced today the successful completion of joint H.248 interoperability testing, providing carriers a compelling combined solution for advanced IP-based services on copper and fiber networks, and a smooth and cost effective migration to converged packet-based access networks based on IP Multimedia Subsystem (IMS) standards. The integrated solution has been welcomed by joint Calix and MetaSwitch customers such as innovative service providers PCS1 and MNSi.

Focused on the small to medium business market, Southern California-based PCS1 is one of the country’s leading competitive local exchange carriers (CLECs). The company is leveraging the combined solution from MetaSwitch and Calix to streamline the transformation of its core network to voice over IP (VoIP) while continuing to provide traditional telephony service.

“MetaSwitch and Calix individually provide state-of-the art solutions that address key pain points for PCS1 as our customers migrate to IP-based communications services,” said Devin Semler, CEO of PCS1. “Together, the combination of Calix and MetaSwitch has greatly improved the reliability of our network and rapidly decreased the time it takes to turn up a new central office compared with the previous generation of access technologies. With more than 75 central office conversions now under our belt, we feel very comfortable with this technology.”
