SIP Trunking vs PRI

Irish-Telecom-IG-v1-Mar-2016

When it comes to delivering voice and data into businesses, IT policy makers usually have two trunking options from which to choose – SIP (session initiation protocol) or PRI (primary rate interface). The decision as to which is the better option boils down simply to which one is more appropriate for your business.
In a nutshell, SIP uses a virtual connection for establishing a voice communication session on a data network, whereas PRI involves a physical line with 23 voice channels and a single data/control channel. There are several notable differences between the two options in terms of the ease of upscaling and adding capacity, the costs associated with each, the ease with which calls can be rerouted if needs must and the quality of service that each provides.
This infographic by Irish Telecom compares the distinctions between SIP and PRI side by side in a user-friendly fashion so that you can see at a glance which option would be more suitable for your business to implement.
