I am trying to use the Custom Context Module (v 126.96.36.199) on our FreePBX (v 188.8.131.52) to restrict some extensions from making outbound and internal calls. I want it to be strictly an emergency phone for 911 dialing.
I created a Custom Context “EmergencyOnly” wherein I allowed only “EMERGENCY” on Outbound Routes, while the rest of the parameters were set to deny. Then I headed over to the “Advanced” tab of one of our extensions to change its Custom Context from “ALLOW ALL (Default)” to the “EmergencyOnly” context I created.
I clicked “Submit” and “Apply Config”. However, after doing so, the extension’s Custom Context returned to “ALLOW ALL (Default)”.
Can anyone please let me know how to make this set-up work? Thank you.
