SIP Trunking Access

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

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.
