A short whisper message plays to the person answering the call before the caller is connected. Know which campaign, source, or offer is calling so you can tailor your greeting and close more deals.
Call whisper plays a short audio message to the person answering the call before connecting the caller, telling them which campaign or source generated the call. CallScaler includes whisper on every plan with text-to-speech or custom audio. Press-to-accept (require the agent to press a key before connecting) is included too, which is critical for pay-per-call because it prevents voicemail pickups from being counted as answered calls. CallRail and CallTrackingMetrics offer similar features but only on higher-tier plans.

Call whisper plays a brief audio message to the person answering a call before the caller is connected. The caller hears normal ringing and never knows. A typical whisper might say 'Google Ads call for roof repair' or 'Facebook lead, water damage restoration.' This gives your sales team instant context so they can tailor their greeting and pitch to the caller's intent. Teams that use whisper consistently report better first impressions and higher conversion rates because the rep is never caught off guard.

CallScaler supports multiple ways to configure whisper messages:
Press-to-accept is a whisper option that requires the answering agent to press a key (usually 1) before the caller is connected. If nobody presses the key, the call moves to the next destination in your call flow. This is critical for pay-per-call networks because it prevents calls from being answered by voicemail systems, which would count as a connected call without actually reaching a live person. It also ensures agents are ready and attentive before the caller comes on the line.
Agencies managing multiple clients on shared phone teams use whisper to identify which client the call is for. The rep hears 'Call for ABC Plumbing, Google Ads' and answers with 'Thank you for calling ABC Plumbing, how can I help you?' without any confusion. Pay-per-call networks use whisper to tell buyers which offer the call belongs to. Solo operators handling multiple business lines use it to switch context between different services. The pattern is always the same: give the answering party context before the conversation starts.
Make your whispers clear and useful with these guidelines:
Without call whisper, your team answers every call blind. They do not know if the caller found them on Google, Facebook, or a billboard. They do not know which service the caller is interested in. This leads to generic greetings and missed opportunities to personalize the conversation. Whisper gives your team the context they need to make a strong first impression on every call. Automatically, with no effort from the caller.
Agencies managing calls for multiple clients use whisper to tell the answering team which client the call is for. A shared receptionist hears 'Call for ABC Plumbing from Google Ads' and answers accordingly. This eliminates mix-ups and lets you route calls from multiple clients through a single phone team while maintaining a professional, client-specific experience.
