SIP Trunking

Providing SIP trunks to enterprises is one of the fastest growing market opportunities for service providers. SIP trunk penetration rates are growing rapidly in every region of the world. However, there are still tens of millions of lines to convert and competition for existing deployments is growing. That’s why Ribbon is investing in differentiated SIP trunking solutions enabling providers to stand out in a crowded market and help them reduce margin erosion. In addition, if a service provider doesn’t want to build their own solution or needs connectivity outside of their region, Ribbon has turn-key SIP trunking as a service (STaaS) offers.

Ribbon offers multiple SIP trunking solution options, designed to work independently or in concert with each other, depending on a provider’s market requirements and existing platform investments. Deploy one or multiple solutions including:

  • Core SIP security
  • Enterprise edge security
  • Intelligent session control and routing
  • Microsoft-certified SBCs for Teams and Skype for Business
  • Value-added services for Teams and Skype deployments
  • SIP Trunking as a Service (STaaS)

Leverage Existing Ribbon Investments

Service providers with existing Ribbon investments in soft switches, application servers, routing engines, SBCs, gateways or enterprise edge devices can leverage these to create new SIP trunking offers. They can also add new elements to enhance the breadth or depth of existing services.

SIP Trunking Access

Ribbon’s session border controllers (SBCs) are the foundation for secure VoIP connectivity between an enterprise and a service provider. The same platforms can resolve SIP interoperability issues and transcode media. Learn more about the features and benefits of the Ribbon SIP Trunking Access solution.

SIP Trunking For Microsoft Teams Calling

Enterprises wanting to add Microsoft Teams Calling capabilities can choose to use Microsoft Calling Plans or they can procure their own SIP trunk solution. Service providers can tap into this market by offering SIP trunking to connect to the Microsoft Phone System through Direct Routing.

Leverage an Intelligent Edge to Reduce Costs

An EdgeMarc Intelligent Edge eSBC can greatly improve installation efficiencies for SIP trunking implementations. Ribbon has fully tested and certified the EdgeMarc with all leading IP-PBX and IP endpoint manufacturers, ensuring interoperability. Automated provisioning capabilities within the EdgeView Service Control Center allow a device to pull down its specific configuration, reducing the steps an installer needs to implement. And of course, an EdgeMarc has the security features needed for successful SIP trunking implementations, such as topology hiding and DDoS protection.

Extending the Value of SIP Trunks With New Services

Ribbon’s Application Server (AS), deployed standalone or in concert with a C20 softswitch acts as a SIP registrar and feature server. Leverage Ribbon’s AS to add simultaneous ring, find me follow-me, centralized directory or enterprise-wide dial plans to a SIP trunking deployment. Providers can also use the AS and C20 to provide additional telephony services for Skype for Business and Lync 2013 deployments.

SIP Trunking as a Service (STaaS)

Leverage Ribbon’s Kandy cloud to offer SIP trunks outside of an existing service area or use Kandy STaaS as a way to rapidly deliver a differentiated service in an existing service footprint. Kandy STaaS includes a complete web portal experience so end customers can logon, order and deploy SIP trunks in minutes. Kandy STaaS is an ideal solution for service providers that have grown through acquisition and need to create a uniform solution. There is no reason to wait years to consolidate existing infrastructure. And, Kandy STaaS works in concert with Ribbon's cloud UC offer Kandy Business.
