Why Forward BT Business Calls to an AI Receptionist?
Forwarding can extend your existing BT Business number into a dedicated answering workflow. That gives your team a consistent destination for calls it cannot answer directly.
What an AI Receptionist Does with Your Forwarded Calls
- Answers callers. Aira can respond to common questions and collect the reason for the call.
- Books appointments. Connect a supported calendar so callers can schedule during the conversation.
- Collects caller details. Capture the information your team needs for follow-up.
- Routes calls. Send calls to the right person or workflow based on your configured rules.
- Keeps call handling consistent. Apply the same approved answering instructions whenever calls reach Aira.
Forward your BT Business calls using the provider-specific steps above, then place a test call before relying on the new routing.
