Short answer
A whisper message is an automatic announcement for the answering person before caller connection. The agent should let it finish before greeting. It helps recognise context but does not independently establish correct attribution or replace the source record.
Key verification: The agent hears the entire announcement and the caller receives the greeting after connection.
Sources and limitationsTwo campaigns reach one team and the recipient cannot identify the requested service. A short announcement may provide context before greeting. This guide accepts that audio journey without adding a sales interrogation or equating campaign recognition with an attributed sale.
Documented feature and regional scope
CallRail explains an announcement heard only by the answering person before connection. It should finish before greeting. Check number and regional availability; this is not presented as contracted Spanish telephony.
A useful minimal announcement
Original example: “Maintenance enquiry”. Identify useful handling context without personal details or a commercial promise. Avoid lengthy internal explanations unnecessarily extending connection. Keep wording tied to the number and current configuration, particularly when reusing a line for another campaign.
Two-participant test
| Moment | Agent | Test caller |
|---|---|---|
| Pre-call announcement | Listens until completion | Records received audio |
| Connection | Greets after announcement | Confirms complete greeting |
| Campaign change | Checks updated wording | Repeats authorised call |
Retain expectations and observations: this table is not a completed test. If the agent greets early, investigate whether the caller missed the beginning. Correct wording inconsistent with the number before relying on its context.
Retain evidence without overstating results
Link announcement, number and observed record; agent recollection does not replace campaign data. CallsIQ has not tested this CallRail configuration. At low volume a visible workstation label may suffice when it identifies the line without delaying or confusing handling.
