Script - Snom phone Action URL to FusionPBX Caller ID

[EasyBB]

I use this script to gather caller id information from my colleagues.

This script is written to work with Snom phones but can be modified to suit any phone that can hit an http url when certain events happen on the phone. I use Snom's "Incoming Call/ On Connected" Action URL field to fire this script. Obviously you'll be able to extend this script to do many more things than just sending emails. You'll also need to adjust the URL depending on where you put this script on the server.

Just a word of caution: If you are on a VPS or have a public IP on your PBX, please make sure the script is NOT writable by www-data or the user running the web server.

Please refer to my mods to the Caller ID Lookup also: http://www.fusionpbxforums.com/threads/caller-id-lookup-cidlookup-from-contacts.20/

/**
 * getcontact.php    v17041501    contributed to fusionpbxforums.com by EasyBB
 * This PHP script is indended to be used for getting caller info from a Snom phone
 * and then sending an email requesting the caller name in case we don't have
 * the caller in the FusionPBX/other contacts database.
 * Snom phone's appropriate action URL must be configured to send the request to this script.
 * See example below:
 * Action URL: http://your-web-server/contact/getcontact.php?cname=$display_remote&extension=$user_name1
 * Prerequisites: PHP 5.4+, MTA (postfix, sendmail etc), Linux
