If you will have agents in multiple queues, and would like them to be able to identify which queue the call is coming from, you can set Caller ID Prefix to a short text string which will show on the receiving handset as part of the Caller ID. For example, if this is set to SUP and a call is received from 0712345678, the handset's caller ID will show SUP 0712345678. In the Queue Timeout field, select the maximum amount of time a caller can be in the queue before they are sent to the mobile overflow.
Generally, people that call and leave messages are more likely to be ideal customers of your business. Your voicemail message is often not much more than a formality to the person calling. Your message is a period of time that they are forced to wait through in order to do what they called to do in the first place — relay information to you.

This is the message that your customers hear when they call during business hours. Greetings often have a short welcome message and list the menu options.
The phone you use to record your greeting – and your surrounding – can turn your carefully scripted greeting into an unprofessional mess. Background noise is terribly distracting, so choose a quiet room or parked car to make your call. Landlines, or a “wi-fi enabled” cellphone call, can provide much better connection quality than a standard cellphone. If you must use a cell phone, be sure to use a high-quality headset for the best clarity.
