Ribbon's SIP Trunking solutions are supporting millions of SIP trunks, across the globe. Our portfolio allows you to choose highly scalable and redundant solutions for the access network as well as cost-effective options to extend SIP trunking onto the enterprise premises as a managed service.
The starting point for SIP Trunking is a Session Border Controller for secure VoIP connectivity between the enterprise and the Service Provider, but can be so much more. Adding in the ability to provide session management as a dynamic SIP registrar, policy control, and routing optimization enriches the offer.
With a wide range of solution options -- turn-key hardware, fully virtualized software or even SIP Trunking as a Service from the cloud, you can choose the scale that matches any deployment requirements, from less than 100 concurrent sessions up to 100’s of thousands of sessions across millions of ports/users.
