Access Solutions for Businesses

With simplified network operations, improved ability to enable productivity applications and cost savings as their goal, many enterprises are looking to converge their voice and data networks by migrating from leased Primary Rate Interface (PRI) lines to broadband Session Initiation Protocol (SIP) trunks.  However, enterprises are also reluctant to completely cut the cord on dependable PRI connections and risk introducing IP-based security vulnerabilities into their voice communications.  With Sonus solutions, service providers can offer enterprises the best of both worlds: G.711 (or better) voice and call control in a SIP trunk solution, a scalable platform that allows enterprises to gradually migrate from PRI to SIP user by user, and a secure network border powered by Sonus' advanced SBCs.

  • Interwork media codecs and signaling between service provider and enterprise networks
  • Deliver a scalable platform that allows enterprises to gradually migrate from PRI to SIP user by user
  • Provide secure network access to and from the enterprise network
SIP Trunking from Sonus is the smart way to grow:

  • Manage dial plans, security and Quality of Service (QoS) levels centrally and therefore more effectively

  • Broad interoperability with a wide range of PBX and IP-PBX devices
  • An enterprise-wide voice Virtual Private Network ("On-net") solution with robust security features
