Find current and accurate SIP Trunk pricing from all service providers in your area. A SIP (Session Initiation Protocol) Trunk works with a PBX system to deliver voice transmission through Internet networks allowing the user to make and receive a larger volume of phone calls at lower prices. Unlike traditional VoIP PBX systems running on the Internet, SIP trunks have less data loss, particularly useful for call centers and large capacity phone operators.

SIP Trunks run on VoIP and/or PBX systems, so the voice signal must be converted from an analog signal to a digital signal. A SIP trunk system conversion is relatively inexpensive compared to adding copper lines. Installation times vary from a few weeks to a few months, depending on the scope of the project. Cost depends on many factors, including proximity to T1 or T3 hubs, installation and ground breaking costs, as well as cost of hardware and software installation.

Analog voice calls used to run on copper wires, meaning one voice call per line. As businesses grow, it would be expensive to add more lines for each additional phone. Installing a larger, digital-capable line like a T1 line is also expensive, but a T1 becomes less and less expensive the more SIP Trunks are added. A specialist can help you to determine the most cost effective method for your present and future call capacity needs.
