We want to integrate WhatsApp Business API, Facebook Messenger, and SMS into the 3CX chat system using Twilio as the primary communication bridge. The goal is to allow all messages (WhatsApp, Messenger, and SMS) to appear and be managed directly from the 3CX chat interface.
The integration should be reliable, secure, and compliant with Meta and Twilio requirements.

Connect a verified WhatsApp Business number through Twilio’s API.
Route incoming and outgoing WhatsApp, Messenger, and SMS messages into the 3CX chat system.
Ensure messages sync correctly (two-way communication).
Maintain message logs and delivery stability.
