In this case study we bring our internet skills to traditional telecommunications, in a project we dubbed the RoboBouncer. RoboBouncer is a bot that screens your phone voice phone calls by asking for the user to speak there name, it then calls you plays the recording and provides you with an option to accept or reject the call.
With full programmatic control of call handling, the possibilities the internet brings to traditional calling are endless. We have set up phone IVR systems (Company Directories), Lead Transfer Systems to High Volume outbound calling.
To test out the RoboBouncer you can call our phone number (949)446-1716
After popular demand we made a commercial version that automates the deployment of a RoboBouncer. Click here to create your own RoboBouncer
For the technically inclined we have posted the code and info at BitBucket
Creating a telephone call screening service using Twilio
The Call Flow
-Caller calls your Twilio Number. The agent will ask the caller to speak there name and record it. Then place the caller in enquene (Inbound Call) -Using Twilio REST API initiate an (outbound call), from your Twilio Number to your personal phone number. Plays the recording, and presents you with the following options:
Press 1 (DTMF) or Say Accept (SpeechResult) -connects the call to Caller using Dial Queue Verbs -OR- Press 2 (DTMF) or say Reject (SpeechResult) ->Using REST API we notify the caller and end the call enqueue and hang up our call
Uses TWIML API and Twilio Voice API PHP SDK
Uses Queue https://www.twilio.com/docs/voice/api/queue-resource and EnQueue to place caller on hold. Could use Conference verb as well instead of Enqueue, just replace Enqueue with Conference for more options
