We are using Twilio’s TaskRouter as a front-end Call Queue Manager for incoming calls, but we are using FreePBX/Asterisk as our in-house PBX. When FreePBX extensions make/receive calls we need to let Twilio know wether the user is available to receive a call from the TaskRouter queue. We have currently devised the following dialplans in the extensions_custom.conf file.
The script works, but since I’m new to custom dialplans, I’m looking for recommendations or suggestions on how (if) this may be accomplished in a better way.
Basically, the idea is to send the called and calling extension numbers to a PHP script, which in turn calls a script over on Twilio to change the “worker status” accordingly to “call” or “wrapup”.
Thanks for any insight you may provide.
