On Hold Putting a call on hold: Many telephones are equipped with a button, often red or orange in color, which enables you to put a call in progress on hold. This means that the call is still at your telephone. The caller cannot hear you, SO you are free to do other things such as call someone else, take another call, search for a file or gather your wits. Multi-line telephones almost always have a hold button. Some single-line telephones have one as well. Some telephones have hold recall, which signals you with a ringing or other sound when you have left someone on hold too long. Other telephones have individual hold, or I-hold. This means that if you put a call on hold at your telephone, no one else in the office that has the same line or extension can take the call off hold from any other telephone. 44 N The Telecom Handbook CHAPTER 2 When a call is on hold, the light on the telephone where the call is holding rhythmically flickers to distinguish it from a call in progress (usually a steady light) or a new ringing call (light flashing on and off).

You announce that you are going to transfer the call to the person at the other extension, and when you hang up, the call is transferred. If you do not announce the call and the extension to which you have sent the call does not answer, the caller may end up back at your desk, at the switchboard or in Voice Mail. This dep
