Give Your Business a Powerful Voice

From traditional telephone service to efficiency-boosting VoIP, CenturyLink helps you stay in touch.

Get voice options for the unique ways you work.
With an efficient mix of time-tested voice services with updated features, we give you a wide range of options. Choose standard telephone services or comprehensive unified communications systems that integrate voice, video and data applications over the same connection. Or go for a hybrid solution that gives you the best of both worlds.

Do business, uninterrupted.
Every customer interaction is a chance to strengthen the relationship. And when people need to reach you, your voice services have to work. No exceptions. CenturyLink has 30+ years of matchless reliability in voice services and business continuity—with virtually 100% dial-tone availability and superior voice quality.

Reduce the costs of great communication.
A traditional voice solution from CenturyLink can help you reduce costs. It has no incremental capital expenditure, and it typically works with the equipment you already have. What’s more, with a relatively simple equipment upgrade, you can extend the life of your existing network by years. When looking for a voice service provider, CenturyLink has your business covered.

911 & Public Safety Services
911 NET

911 subscribers can easily make critical database changes and receive rapid, electronic confirmation. 911 NET also provides a current online copy of the 911 subscriber's Master Street Address Guide.

Key applications: public safety answering points (PSAPs) and Enhanced 911 call centers

911 Subscriber Records Information

CenturyLink simplifies response by giving 911 subscribers a complete listing of CenturyLink customers in their area. Non-CenturyLink and unlisted customers are not included, so the information is not considered sufficient for full 911 maintenance.

Key applications: Public Safety Answering Point (PSAP), Basic or Enhanced 911 call centers

Enhanced 911

Three features give your locality the best 911 system:

  • Selective Routing (SR) allows 911 calls from different telephone numbers with the same prefix to be routed to different PSAPs, based on the caller's address
  • Automatic Number Identification (ANI) identifies and forwards the caller's telephone number to the PSAP
  • Automatic Location Identification (ALI) provides the caller's address and related information to the PSAP

Key applications: PSAPs and Enhanced 911 call centers

CenturyLink® Managed Emergency Call Handling

Today’s public safety answering points (PSAPs) are being asked to keep up with the evolving ways citizens want to ask for help. Traditional wireline 9-1-1 calls are decreasing while calls from mobile devices, video and even text messages are increasing. To help dispatch centers adapt, we offer a configuration of E9-1-1 to hosted calling handling applications designed to help PSAPs adopt new technology and predictably manage their operating expenses.

Emergency Transport Backup (ETB)

When dedicated 911 lines fail, CenturyLink prevents the problem from creating an emergency itself. Our backup systems use alternate transport paths, including the public switched telephone network and wireless, so no emergency call goes unanswered.

Key applications: PSAPs, Basic or Enhanced 911 call centers

Private Switch/Automatic Location Identification (PS/ALI)

CenturyLink has the power to let you identify an exact phone station within a company or large building. If the customer has a properly equipped PBX or Centrex system, CenturyLink lets you identify the phone extension, even if the caller is on a private switch. This can help bring order to a potentially chaotic emergency situation.

Key applications

  • Multi-Tenant buildings served by a single PBX
  • Campus environments
  • Remote locations
CenturyLink CPE Public Safety Solutions
