A common question that pops up is what is the experience when a PBX concurrent call limit is reached and how to best monitor for how often a limit may be reached...
What is the experience when a limit is reached?
From an outside caller calling into the PBX if a limit is reached they will hear a busy signal.
For an inside caller calling out they will receive a message "License limit reached. Please contact your system administrator."
How do you monitor for limit reached events?
In the phone system settings:
V14 - Settings, Email, License Limit Reached - Check box and press OK
V12 - Settings, General, Email Notifications, License Limit Reached - Check box and Press OK
Important
In all cases make sure to put in at least one email address in the notification field at the top of the page. You are able to list multiple emails if you choose. It's not uncommon for alerts to be sent to a help desk, ticketing, or PSA system to a set ticket board so that you can monitor alerts from multiple PBX instances in one place.
A Gotcha and Work Around
If you use the same email address to send alerts too like alerts@myitcompany.com it can be very difficult at times to distinguish what alert came from which PBX. A work around of creating an email alias for each instance so that when alerts come into the single mailbox, ticketing board, etc it will be very obvious what alert came from what system.
