We will employ this proven service to deliver VOIPTS to Agencies. Qwest is well positioned to offer Voice Over Internet Protocol Transport Services (VOIPTS) to Federal Agencies using Qwest’s commercial OneFlex Voice Termination solution. Qwest’s VOIPTS is an Internet Protocol (IP)-based solution that rides on Qwest’s National Network System (NNS) and leverages Qwest’s worldwide Long Distance (LD) network. The service uses Voice over IP (VoIP) technology but also permits traditional Time Division Multliplexing (TDM) interface through a common gateway architecture. The VoIP capability of Qwest’s VOIPTS provides termination of voice calls over compliant voice telephony solutions via Public Switched Telephone Network (PSTN) connectivity. Qwest’s VOIPTS supports PSTN termination to all domestic LATAs including both fixed and mobile termination. The system supports on-net terminations that can be to either VoIP-enabled locations or TDM dedicated terminations. This includes combinations of VoIP on-net to on-net and VoIP on-net to off- net. Qwest has used IP and the Qwest core Multi-Protocol Label Switching (MPLS) network to carry LD voice traffic since 2001. The Qwest network currently carries of IP-based voice traffic.
