The Challenge
Managing phone menus, call forwards, ring groups, and custom voice routing rules typically requires expensive call center software or writing custom code for every change. The client wanted a simple, visual, web-based platform that allows business owners to provision phone numbers, configure IVR call menus, and manage ring groups dynamically without touching code.
The solution had to be highly reliable, handle concurrent calling surges, process voice mail transcripts, and automatically trigger text message follow-ups when calls go unanswered.
The Solution
We built a visual call-flow routing builder that compiles user configurations into structured JSON routing schemas. Our PHP backend reads these schemas on demand to generate dynamic TwiML (Twilio XML) responses to route incoming voice calls in real time.
We engineered an asynchronous task runner that monitors call state changes, coordinates ring groups, transcribed voicemail recordings via speech-to-text APIs, and fires SMS triggers instantly using Twilio’s messaging endpoints.
Technical Architecture & Highlights
Allows users to configure multi-level voice response systems (e.g. 'Press 1 for Sales, 2 for Support') using a drag-and-drop hierarchy canvas.
Detects when a customer call is missed or dropped and immediately sends a customized follow-up text message to save the lead.
Coordinates simultaneous ringing across multiple agent phone numbers or sequential routing to ensure calls are answered promptly.
Processes voice recordings, generates transcriptions, and delivers them via email or SMS notifications directly to business managers.
