SIP Trunk

Business SIP Trunking Solutions

Integrate Both Voice and Data onto a Single, Converged Network.

You've taken the first step toward a converged network solution by purchasing Qwest iQ® Networking service, which includes a multi-protocol label switching (MPLS) IP-based wide area network. Now it's time to take the next step and complete your converged solution, integrating voice with your data by adding Qwest iQ® SIP Trunk—a tested secure and reliable IP telephony solution. You've heard about the risks of adding voice to an IP network—that it's not secure having your calls travel over the Internet. However, Qwest iQ SIP Trunk provides features which support redundancy to help protect customers through voice switch or IP network failures, and can be purchased with Qwest iQ Networking Private and Enhanced Ports, so your calls can be delivered securely over our MPLS network. With SIP Trunking, you gain all the security and reliability of MPLS without requiring expensive overhauls to your current infrastructure. Instead, you can expand your operations to sites all over the continental U.S. at a minimal cost. You also get your voice and data delivered over one of the most advanced networks available, Qwest's application-aware OC-192 data backbone, supported by a competitive service level agreement (SLA).

How SIP Trunking Works

As a SIP Trunk provider, Qwest is able to route voice calls from your IP-PBX across secure MPLS communication paths using Session Initiation Protocol (SIP)—a signaling protocol that delivers real-time, IP-based communications. Depending on where the calls terminate, they are either delivered to the Local Exchange Carrier in the customer's area or delivered off-network as a domestic or international long distance call. For calls to existing Qwest® VoIP subscribers, they are delivered on-network, which avoids ordinary toll service fees for domestic long distance calls.
