SIP Trunking

  • Deliver enterprise PBX connections using VoIP
  • Replace managed services with hosted offerings
  • Reduce costs and add compelling new UC services

What is it?

SIP trunking replaces classic TDM enterprise voice connections with a voice over IP (VoIP) service that shares the broadband connection employed for data and internet. This dramatically reduces the cost of delivering telephony services while eliminating the step pricing increases with capacity growth. SIP trunks enable operators to easily enhance their offerings with hosted unified communications and collaboration.


How do we help?

Our SIP trunking solution is built on the MetaSphere Call Feature Server (CFS) and Enhanced Application Server (EAS). The combination of these platforms enables operators to deliver anything from a simple business telephony service to a comprehensive UC solution. The Perimeta SBC is also typically added to a SIP trunking solution to protect both the operator and enterprise network. 


When to contact us.

Are you currently managing premise-based PBXs using legacy TDM trunks? Do you want to offer hosted alternatives, as these products reach EOL or become increasingly expensive to support? Are your customers asking to augment their basic business lines with unified communications? Our SIP trunking solutions are ideal for enterprises of all size, so join the hundreds of operators that are deploying them.
