I am looking for a person who can make an extenspy module or basic code to allow someone to enter a code to listen to a specific extension.
Here is a workflow:
Ext 1 wants to hear Ext 2's conversation without being able to input audio.
Ext 1 presses a single feature button on a sip phone (Grandstream GXP2000) or dials a single code that is coded specifically to hear only Ext 2
Ext 2's inbound and outbound audio is heard in Ext 1's handset.
I am currently using FreePBX Distro and would like it built into that, whether it is via a custom module or through direct placement of code in a conf file, etc.
