Monitor multiple time conditions (If-then-construct)


(Reinhard) #1

Our freePBX system uses 3 time conditions, which set the route for the incoming calls (main company number).

  1. *271 24h-service
  2. *272 holiday
  3. *273 standard business hours

TC1 non-match links to TC2, which in case of a non-match links to TC3.
TimeCondition 1 and 2 are connected to online calendars using the new calendar module. TimeCondition 3 uses a TimeGroup (Mo-Fr 8-18h, Sa 8-12h). The holiday online calendar generates Austrian holiday dates and the 24h-service-calendar contains, in our case, a 24h-event every 9th day.
Based on this setting with these 3 TimeConditions, one can cover almost all possible scenarios. A 24h-service-event overrules both other time conditions. A holiday-event overrules the standard-business-hours.

Now…the problem!
It is not possible to monitor the freePBX phone system with multiple time conditions. Are we open or are we closed? You cant tell…

I don’t know how to write a php script, therefore I used the script from lgaetz ( https://gist.github.com/lgaetz/8545099 ) and adapted it.

This is my current script. It gives you the following outputs in the terminal (which can be used to display it on a phone): 24h-service, holiday, we are open, we are closed

timeconditions.php

Ideas, suggestions, corrections and thoughts…are welcome :wink:

You are including the freepbx framework so you don’t need to start another ami session. Just use the ami that is already provided to you and already logged in

$astman = FreePBX::create()->astman

There is no need to connect either. It’s already connected.

I see…thanks…problem is that I don’t know nothing about php (and AMI). I just searched for some php commands which would extract the combined extension state info out of the arrays…and played around with them until I got it working…
I still wait for my Digium D65 and will try to implement it later.

EDIT: I will try to remove all the remote-server stuff, later in the evening.

Currently working on this script, which is still rough, but you can probably adapt it for your purposes

Wonderful…thank you so much!!!
