Hi I am trying to find the best way to monitor my extensions in Nagios. All our phones are DHCP so have ever changing IP addresses. Going down the route of fixing all their IP addresses will be a very last resort. I would like a way to query the 3CX phone system for the status to an extension (the status as is visible in MyPhone or the Extension Status page of the Management Console) I dont mind what technology the query needs to use http, command line etc. just as long as we can script it so Nagios can find out if extensions are logged on and alert us if they go offline. Many thanks for any help or ideas.
