Service Network

Our service delivery network ensures that you have the highest reliability and connectivity. This document outlines the details of our network along with IP address records for advanced use case scenarios or specific firewall filtering situations.

Reliability

We have four datacenter locations across the United States for a highly reliable, redundant, and scalable system. If one region goes offline your connection will reroute to another location automatically. You don’t have to worry about a local power outage or an ISP (Internet Service Provider) outage affecting your calls either. The softphone application integration allows you to continue using the system without interruption. In addition, the Prysm Voice platform includes intelligence to determine if any of your phones disconnect and will route incoming calls to a predefined destination such as another user, voicemail box, auto attendant, call queue, or external number.

Scope

As a general matter, you will not need to do anything with these IP addresses, because the provisioning servers will take care of SIP Device configuration. We will provide you with domain names that will resolve to these servers as necessary.

IP Addresses for Voice Services
