I have a cluster of Mitel 3300 ICP PABX’s across several offices internationally and have been looking for a monitoring solution that can send alerts whenever an alarm is triggered on any one of the PABX controllers. Mitel already have a monitoring solution called Enterprise Manager, but this didn’t do what I wanted it to do. Enterprise Manager will send out emails based on certain policies and allow for issue escalation but its features are a little limited. I already have an extensive Nagios setup that will SMS and email for alerts, so I looked at integrating with this system.
