Hi Brian,

To delete the "Please wait while we transfer your call" message;

For Unity versions prior to 4.1 (and UC 1.x) here is an excellent answer from Jeff @ Cisco;

The nice thing is that this is much easier to change in the new UC 7.X Version;

The ability to change "Record Your Message at the Tone" prompt is not available until UC 7.0;

User Templates Edit Greeting

Play the "Record Your Message at the Tone" Prompt

Check this check box to have Cisco Unity Connection prompt callers to wait for a tone before recording their message.

Default setting: Check box checked.

From this good doc;
