SIP Trunking vs PRI

IT specialists may have vastly different opinions on the merits of SIP (session initiation protocol) trunking in comparison to PRI (primary rate interface). While both are used for the function of delivering voice and data into businesses, and companies often use a combination of the two to good effect, each comes with owns strengths and weaknesses in terms of costs, ability to upscale, capacity planning, ease of continuity and quality of service. The following infographic illustrates an easy to understand SIP versus PRI guide to readily compare between the two options. Generally, SIP is used for establishing a voice communication session on a data network, e.g. over the Internet. On the other hand, a PRI is a single line with 23 voice channels and a single data/control channel. In the infographic below you will read how both protocols work and additional information regarding hardware and backup. What is more, capacity planning and business continuity are considered as well. Which is the better choice? Read the infographic and make your choice or combine the two.
