The WBG wishes to invite bids from a Service Provider that provides enhanced, innovative and industry leading Session Initiation Protocol (SIP) trunking and transport technologies that can replace the existing SIP trunks. The Service Provider is required to support SIP sessions in a highly available, redundant and load balanced solution.

  • Must meet the requirement for a geographically distributed, active/active and load balanced design for SIP Trunking Services across WBG data centers.
  • Bidder must be a Tier 1 service provider and own, maintain and operate their own private IP network. A Tier 1 service provider owns and operates its own proprietary IP network and does not require 3rd party owned networks to deliver IP based (SIP) services to its customers.
