Migration to SIP


More and more businesses are looking to lower their costs and implement Unified Communications (UC) in their network. Session Initiation Protocol (SIP) enables enterprises to consolidate their network into a single, Internet Protocol (IP)-based network that can handle voice, video, and data traffic over the same connection. Sonus' Session Border Controller (SBC), policy and management solutions allow a seamless migration to SIP by providing enterprises the ability to:

  • Secure the Network - the move to SIP requires a network security element to protect the enterprise from malformed packets and Denial of Service (DoS) attacks
  • Consolidate Policy Management – set routing and dial plan policies at one time for the entire network
  • Enable UC – enable real-time communications including: voice, video, instant message, multi-media conferencing, user presence information and data sharing applications
  • Reduce Costs – lower equipment costs and long distance service fees
  • Increase Network Reliability and Resiliency – reroute calls during power outages and natural disasters
  • Migrate Existing Analog and Time Division Multiplexing (TDM) devices - any-to-any connectivity between TDM, H.323 and SIP devices, enabling enterprises to rapidly migrate analog phones onto SIP-based networks
  • Scale – easily scale capacity requirements as voice and video demands increase by adding sessions when you need them
