Let's say you wanted to notify all phones that a Lockdown scenario has started or 911 was dialed at this location. We would need to find all registered phones and push out a message.
a) Person dials the predetermined emergency number
b) CME Syslog see this event and runs the Event Manager applet
c) The CME uploads the TXT file to the Windows server and the PowerShell script sees the new file and runs the PHP script.
d) The PHP script then reads each line of the uploaded TXT file and pushes out the XML file to the registered phones.
See the start of the event manager applet on Part 1.
Find all register phones (SCCP and SIP) and add them to an variable
