SAN FRANCISCO -- Metaswitch Networks, a leading provider of carrier infrastructure and software solutions, today announced that it successfully participated in the MultiService Forum (MSF) Voice over LTE (VoLTE) Interoperability Test Event 2011 with the Perimeta™ Session Border Controller (SBC).

Hosted by the MSF, and backed by GSMA, September's event was jointly hosted by Vodafone at their Düsseldorf Test and Innovation Centre and by China Mobile at their Research Institute Laboratory in Beijing. Leveraging interworking interfaces and functional components defined within the 3GPP IP multimedia Subsystem (IMS) standards, Metaswitch was one of a select group of companies validating this approach to delivering voice services over LTE infrastructures. The Perimeta SBC functioned as a P-CSCF in both local and roaming scenarios, involving a number of vendors' PCRF, I-CSCF, S-CSCF, diameter routing agent and User Equipment (UE) implementations.

"The MSF VoLTE Interoperability event reflects the MSF's commitment to carrier-driven interoperability events that validate key emerging standards and technologies, including key network interfaces that ensure multi- vendor deployment strategies for LTE/EPC/IMS technology. We are delighted that Metaswitch participated at the 2011 event," said Kyu-Ouk Lee, MSF President.
