A transfer is not complete because the receptionist dialed a teammate. The caller still needs a clear outcome when that teammate is busy, declines, or cannot be reached.
Write the destination and the failure path together
For each transfer reason, name the destination, coverage hours, ringing window, and alternate contact. Then decide what Nova should say if no human answers. An approved message, voicemail, or safe fallback is part of the flow—not a patch to invent during a live call.
Rehearse what the caller actually hears
Place customer-approved test calls and deliberately let the receiving phone ring out, reject one call, and make one destination busy. Confirm the caller is not left in silence or dropped after a promise to connect. Ask a human to answer another call and confirm that the right caller context reaches the team.
Record the outcome without implying completion
The workspace record should make a distinction between transfer requested, transfer attempted, and transfer connected. If the attempt fails, retain the callback details and assign a human owner. Do not mark a request resolved simply because a number was dialed.
Watch for forwarding back to the start
If a business number conditionally forwards to the receptionist, a transfer back to that same path can create a loop. Test the actual carrier, destination, and after-hours settings with the customer before enabling the route. Use an agreed distinct human destination where needed.
Approve a plain-language fallback
A useful fallback acknowledges that the person could not be reached, offers the approved next step, and avoids a guaranteed callback time unless the business has authorized one. Twilio's voice documentation distinguishes answered, busy, and unanswered dial outcomes; implementation details must be tested in the customer's configuration.
