A WhatsApp message finishes yesterday's call
Life Insurance
A policyholder rings at two in the afternoon about a renewal date, then messages on WhatsApp that evening asking for the document itself. The customer key matches the mobile number to the call record, the afternoon conversation is retrieved into the agent's context before it replies, and the document goes out in the very next message without anyone asking which policy they mean.
The second contact is one message long instead of a re-explanation. Both sit on one conversation record, so quality review and reporting see a single customer rather than two.
