SIP Trunking

SIP Trunking is increasingly implemented by businesses across the globe as they seek to reduce costs and improve service agility.  However, many enterprises are struggling to rationalize disjointed multivendor PBX environments that are difficult to maintain, let alone extend. Service providers can turn these challenges into opportunities by delivering service offerings that transform fractured corporate telephony environments into cohesive enterprise-wide IP communications systems. Ribbon provides solutions for every facet of SIP trunking including:

  • Security (media and signaling)
  • Session mediation and media transcoding
  • Intelligent session control
  • Overlay applications and services

Solutions for the Core or Edge

Ribbon Session Border Controllers (SBCs) and session controllers are supporting millions of SIP trunks, across the globe.  Choose highly scalable and redundant solutions for the core as well as cost-effective options for the enterprise premises.

Turn-key Hardware or Software-only Solutions

Ribbon offers a wide range of solution options -- turn-key hardware, fully virtualized software or cloud services.  Choose the scale that matches the deployment requirements, from less than 100 concurrent sessions up to 100’s of thousands of sessions across millions of ports/users.

SIP Trunking Advantages:

  • Extensive interoperability testing and features such as SIP message manipulation
  • Compatibility with a wide range of Time-Division Multiplexing (TDM) PBXs, IP PBXs, SIP endpoints, WebRTC gateways and UC solutions such as Microsoft Skype for Business/ Teams
  • Grow revenues and margins with virtual CPE offerings such as enterprise SBCaaS 
  • Protect customers with Ribbon SBC security features including network topology hiding, DoS/DDoS prevention, encryption and NAT traversal
  • Protect your network with Call Admission Control capabilities to prevent overload conditions.
