Out at Mobile World Congress last month, Metaswitch Networks introduced the Metaswitch SIP Session Router (SSR). It will be available directly from Metaswitch and through an OEM agreement
The SSR is a purpose-built platform built to scale and designed to support 10 million BHCA in stateless, transaction stateful and call stateful modes, allowing operators to provide different levels of service across a SIP signaling network domain.
Metaswitch is positioning the product to allow mobile operators and others to be able to scale up SIP traffic according with the coming all IP onslaught of LTE. The SSR is tightly integrated with Metaswitch’s service assurance server for all that good QoS and network monitoring goodness.
