Disaster Recovery is also known as a process that is implemented between the carrier and customer that allows a customer to have a backup plan in case their Mitel VoIP phone system ever goes down. It provides business continuity and allows you to rest easy. Premises System, Inc. can create a personalized disaster recovery on their Mitel phone system if a phone system does fail. While no system is ever fully “disaster-proof,” ShoreTel’s IP phone system offers several options to continue your business and guarantee productivity. Mitel’s architecture offers their N+1 redundancy option or even the option of backing up their headquarter server. Starting with Connect, this HQ server can be virtualized under VMware VSphere, allowing customers to take advantage of VMWare’s High Availability (HA) and VMotion options.
