SIP Trunking for Enterprises

Many enterprises are struggling to rationalize legacy PBX environments made up of disparate systems that don't interoperate effectively and can't share dial tone services. Ribbon's SIP trunking solutions can transform these same assets into one virtual communications system, with site-to-site dialing and a common service provider. Ribbon's session mediation tools make it easy to connect multiple brands and generations of PBXs together. The results, employees stay connected and the organization can leverage multi-site purchasing volumes to reduce costs. And since it's based on Ribbon's carrier-grade software, the solution will be secure and scalable.

SIP Trunking for Optimized IP Connectivity

SIP trunking gives an enterprise a compelling way to leverage their data-driven IP connectivity for voice communications. Using IP eliminates the distance limitations of legacy TDM (T1/E1) or analog connectivity, making it easier to centralize and rationalize trunking capacity in multi-site environments. The combination of connectivity savings, capacity savings and the opportunity to consolidate total spend with a single SIP trunking provider can result in dramatic savings.

Ribbon provides solutions for every facet of SIP trunking including:

  • Security (media and signaling)
  • Intelligent session control and routing (common dial plans and class of service)
  • Session mediation (solves interoperability issues)
  • Optimized media transcoding to ensure quality of service
  • Overlay applications and services

SIP Trunking for Cloud-hosted Applications

For enterprises who are migrating their unified communications to the cloud, Ribbon's session border controllers (SBCs) can still be deployed on-premises to act as the demarc point for traffic to/from the cloud.  Alternatively, an enterprise may find it more attractive to purchase SBC as a Service from the cloud service provider. Ribbon's SBCs support this deployment model as well.

Certified SIP Trunking Solutions for Skype for Business and Microsoft Teams

Ribbon Communications has the largest portfolio of SBCs certified by Microsoft.  Whether an organization is migrating one site or an entire campus to Skype or Teams, Ribbon can provide a secure Direct Routing solution that retains local services and accel;erates migration. Organizations can choose turnkey Ribbon appliances (e.g., SBC 1000 or SBC 2000) or install software-only versions (e.g., SWe or SWe Lite) on their own hardware.

SIP Security

Using Ribbon's SBCs, at the edge of the enterprise network, secures SIP sessions and protects IP communications infrastructure such as application servers, media servers, and media gateways. However, with Ribbon's Protect solution an enterprise can go beyond secure VoIP and IP multimedia sessions, safeguarding the enterprise network against denial of service attacks, theft, and fraud.

Intelligent Session Control

As a complement to SIP Trunking, Ribbon's intelligent session control solutions provide centralized policies and dial plans for routing decisions related to handling traffic across disparate PBX and/or contact centers platforms.  In addition, Ribbon's carrier heritage ensures our solutions scale across an entire enterprise.
