CenturyLink Connection

Benefits

Cost Savings: With CenturyLink's VoIPTS, your Agency can realize the cost savings of an IP-based network without the added costs of managing a premises-based SED IP/TDM conversion. Other valuable benefits include:

  • Scalable, single point access through CenturyLink's IPS or NBIP-VPNS or across the peered public Internet for both voice and data, versus multiple TDM switch trunks and a separate data connection
  • Allows multiple Agency clients to interface across a common network, eliminating the need for custom one-off solutions for Agencies
  • Fully integrated VoIP product suite for on-net calling between Government Agencies using VoIPTS
  • Leverages existing Key and PBX infrastructure
  • Provides a common communications platform between Agencies, which allows for standardization of VoIP communications

Quality: CenturyLink's IP voice infrastructure provides quality and service levels comparable to traditional TDM service. CenturyLink's VoIPTS comes with 24x7x365 network monitoring and management to ensure nearly 100 percent network uptime and real-time troubleshooting. Your Agency will receive selectable G.711 or G.729 Codec, giving it control of voice quality on a per call or service basis.
