# What each pre-recorded announcement leaves behind

Last verified: 2026-09-15

The 3 pre-recorded message types differ by audience: a compliance message is heard by both the caller and the agent, an agent personal greeting plays at the start of every incoming call, and a whisper announcement plays only to the agent[^7]. A compliance message and an agent personal greeting are included in call recordings, whereas a whisper announcement is not[^2].

## How message types behave

A compliance message is a legal message played once per call at the start of the interaction between caller and agent[^3]. The restriction on holding, transferring, conferencing, and requesting supervisor assistance is stated only for the whisper announcement; neither the compliance message nor the agent greeting carries it in the 2 documents that describe them[^5]. 

All 3 announcement types are supported in the Set Announcement activity in Flow Designer[^6]. An uploaded announcement must be a mono file at an 8 kilohertz sample rate with 8-bit u-law encoding[^1]. 

In the field, the pre-recorded messages documentation carries a sentence that stops mid-clause, 2 misspellings in one procedure, and a 3rd in the Flow Designer copy of the same steps[^4].
