A PRI, or Primary Rate Interface, was designed to free you from the expense and complexities of multiple physical phone lines coming into your business. However, traditional PRI still requires that the cable is physically delivered from the telephone pole to the office building, incurring a lot of traditional phone line charges, and typically has a 36-month commitment minimum and 4-6 week installation timeline.

GreenLink’s SIP to PRI service is delivered by using a local hardware Gateway that connects to the network. The SIP trunks are then configured on the Gateway via the internet and a PRI port is provided to be connected to the PBX.

SIP to PRI is available in 6-trunk increments, each trunk having a 2-channel capacity that can be instantly upgraded until the capacity of each gateway device (24 channels) is reached. For more capacity, additional gateways can be added.
