Solution description

With Metaswitch’s SIP Trunking solution, network operators can replace conventional PSTN trunks quickly and easily and enable enterprise IT managers to take advantage of innovative cloud-based unified communications and messaging services. SIP Trunking combines communications services with other enterprise data on a single common broadband connection, practically eliminating the classic issue of stranded capacity, expensive step-pricing structures and call blocking, due to the lack of capacity during high demand.

Network operators can use our SIP Trunking solutions to reduce their reliance on expensive legacy TDM infrastructure, and to increase revenue opportunities by taking control of high-value business communications services such as mobility, UC and collaboration and by entering geographic regions outside their normal serving areas. Meanwhile, business customers can immediately realize large cost savings from SIP Trunking and benefit from enhanced business services, whether they use simple CPE-based integrated access devices (IADs), premises-based PBX IP interfaces, or all-IP PBXs.

SIP Trunking provides an additional layer of redundancy and resilience during outages or widespread disasters, with automatic failover and load balancing. Moreover, our portfolio of unified communications interfaces and mobility applications enable operators to extend basic telephony offerings with enhanced call routing, instant messaging and collaboration tools. A comprehensive web portal enables users and administrators to configure and manage their individual business communications features.

Guaranteeing interoperability and feature compatibility across a broad array of customer configurations, Metaswitch conducts extensive testing with leading IP-PBX vendors, SIP mediation devices and UC providers, such as Skype for Business. In addition to being SIPconnect compliant, Metaswitch maintains a library of certified IP-PBXs with configuration guides, saving you time during provisioning and installation.

The Metaswitch SIP Trunking solution is built on our MetaSphere Multiservice Telephony Application Server (MTAS) platform. The Perimeta Session Border Control (SBC) augments the SIP Trunking solution with the security a network operator needs to protect the integrity of their network infrastructure and their customers’ networks, while providing the necessary interworking between our state-of-the-art service delivery platforms and older customer premises equipment.
