The problem
WhatsApp and Instagram are where your customers already talk, and where response time is judged in minutes, not hours. Most businesses answer when someone happens to be free: messages sit unread overnight, order questions go stale, and the customer who was ready to buy quietly buys elsewhere.
How CallCast fixes it
CallCast connects your official WhatsApp Business number and Instagram account to the same AI assistant that answers your phone calls. It replies in seconds, in the customer's language, using only facts from your knowledge base. Your team watches everything in a shared inbox, takes over with one click, and hands back when they're done.
What you can do
Answer every WhatsApp message instantly
Customers message you where they already are. CallCast connects your WhatsApp Business number in minutes, answers questions from your own knowledge base, and never invents prices or policies it cannot verify.
Reply in voice notes, not just text
When a customer sends a voice note or asks to hear a reply, the assistant answers with a natural voice note in your agent’s voice. It understands reactions and quoted replies too, and reacts back when a thumbs-up says enough.
Hand over to a human at the right moment
When someone is upset, asks for a person, or needs something the assistant cannot do, the conversation is handed to your team with a summary, an email, and a dashboard alert. Reply from the shared inbox or from the WhatsApp app itself.
Instagram DMs in the same inbox
Connect your Instagram professional account and the same assistant answers your DMs. Story replies, reactions, and quoted messages all land in one place, next to your calls and WhatsApp threads.
Built as messaging infrastructure
CallCast operates the WhatsApp and Instagram integration as a Meta Tech Provider: businesses connect their own numbers and accounts through Meta's official signup flow, keep ownership of their WhatsApp Business Account, and run on Meta's Cloud API, no unofficial gateways, no shared numbers, no scraped sessions.
