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 stranded capacity, expensive step-pricing structures and call blocking, due to the lack of capacity during high demand.

  • Delivers mobility, unified communications (UC) and collaboration services
  • Enhanced call routing and instant messaging
  • HD voice and video
  • Comprehensive web portal for end users and administrators
  • Supports “bursting” for periods of high volume without call-blocking
  • Works with all-IP PBXs, PBX IP interfaces and Integrated Access Devices (IADs)
  • Automatic failover, load balancing and remote office capabilities
  • SIPconnect compliant

Why use Metaswitch’s SIP Trunking solution?

To compete in the lucrative business voice market, network operators must continually enhance their service offerings while constantly striving to reduce costs for both themselves and their customer base.

As businesses move away from traditional TDM-based phone systems to an all-IP environment, they will need to embrace SIP trunking as the standard for voice and multimedia communications. This need will only intensify as older phone systems reach end-of-life and require replacement.

  • Increases revenue opportunities from high-value business communications
  • Enables network operators to enter geographic regions outside their normal serving areas
  • Reduces reliance on expensive TDM infrastructure
  • Business customers can realize large cost savings
  • Tested for interoperability with leading IP-PBX vendors, SIP mediation devices and UC providers
  • Configuration guides for certified IP-PBXs saves time during provisioning and installation
The technology and support we’ve received from Metaswitch allows us to provide a more thorough suite of services for our customers.
