Level 3 Communications launched a new SIP-based (session initiation protocol) platform that enables enterprises to securely connect more sites with greater operating and cost efficiency, incorporating a fully native PRI (primary rate interface)-handoff capability and other new performance-enhancing features.
Level 3 said its Voice Complete solution achieves higher overall efficiency and savings when compared to existing service offerings by including built-in options for disaster recovery, emergency 911 and the ability to connect legacy TDM office sites more easily without the need for equipment upgrades.
- A fully native PRI-handoff option, allowing customers to receive a SIP handoff directly to a TDM (time division multiplexing) private branch exchange (PBX) without the need to purchase or configure additional equipment.
- Geographically independent telephone numbers, simplifying the management of telephone numbers across mobile workforces and providing virtual presence.
- A combination of dedicated long distance and local services, SIP services and ISDN-PRI (integrated services digital network) services.
