Good telephone greetings for a work number consist of the employee's name, company name, a statement that indicates that the employee cannot take the call right now, invitation for the caller to leave a voicemail and when the caller can expect a call back. A good length for a telephone greeting is 20 to 25 seconds.
A good telephone greeting gives the caller the impression that the employee is pleasant and professional. The tone should convey that the employee cares about the caller and the matter he is calling about.
The following are a few examples of good telephone greetings:
