CenturyLink IQ® SIP Trunk: Decentralized Deployment

Rather than consolidate PRIs and POTs, IQ SIP Trunk Decentralized Deployment solutions provide SIP Trunk service at each location and can survive a private WAN failure. It includes direct access to PSTN from each site.

Extend the capabilities of your existing, legacy PBX hardware while converging your separate voice and data networks into a single, robust IP data and voice network. IQ SIP Trunk works in conjunction with CenturyLink® MPLS Networking, providing a private, fully interoperable and scalable suite of wide area network (WAN) services. IQ SIP Trunk delivers increased functionality, improved call quality, better security and simplified network management and is available nationwide. CenturyLink backs its IQ SIP Trunk service with a 100% voice availability SLA. Leverage simple end-user and administrative management portal and robust quality of service (QoS) to help ensure that time-sensitive network traffic is prioritized and routed correctly.
