The call-waiting feature on a phone allows you to answer another call while you're on the line with someone else. The original call is placed on hold, while the new incoming call is answered. This is feature is prominent on many cell phones, and it makes it easier not to miss important calls. Although call waiting is a useful feature, there may come a time when you do not want to have call waiting active. For example, if you are expecting an important call and do not want to be interrupted, you may decide to disable the call-waiting feature on your cell phone.

Call waiting is a telecommunication service offered by a telephone service provider to a subscriber by which the subscriber may suspend a telephone call already in progress to accept a second call. The subscriber may switch between calls, typically by using the hook flash signal.

Call waiting alleviates the need to have more than one telephone line for voice communications.

Star codes[edit]

In North America, the NANP uses the *70 star code prefix to suspend call waiting for a dialed call. A stutter dial tone confirms the de-activation.

On most European telephone networks, and GSM or UMTS mobile phones, call waiting is activated by dialing the following codes:

• To activate: *512*
• To deactivate: #511#
• To check status: *1645#

A voice announcement, tone or a message on your phone's screen will confirm the service status.

Call waiting in Europe uses an 'R' (recall) button on the phone. This performs a similar function to a North American hook flash button but is much shorter duration, typically 80ms to 100ms, vs. 250ms in North America. In some networks, pressing R toggles between the calls, similar to North America. However, in most countries there are further options:

• R1 – Answer the waiting call and hang up on the current call.
• R2 – Toggle between the calls.
• R3 – Merge the two calls for conference calling.
• R0 – Reject call waiting – This will send the call to voice mail or a busy tone.

Type II Caller ID also works with call waiting.

Line sharing[edit]

Since the waiting call creates an audible signal (for example, a 440 Hz beep every ten seconds in North America), call waiting can cause dial-up Internet access connections to terminate, unless the modem supports the most recent V.92 modem standard. For this reason, call waiting is often disabled on shared voice lines used for dial-up modem or fax purposes. However, Call Waiting has no impact on DSL connections.

History[edit]

Call waiting was introduced to North America in the early 1970s when the first generation of electronic switch machines built by Western Electric, Electronic Signaling System 1 started to replace older mechanical equipment in the old Bell System local telephone companies. At first, some smaller municipalities were able to offer customers call waiting only on a specific phone exchange (e.g., phone customers in Trenton, Michigan initially had to have a phone number starting with 671 to have call waiting, since 671 was at that time the only exchange in that area served by one of the new ESS switches), but as demand for it became more widespread, it eventually became available on all phone exchanges as the older equipment was phased out.

In Europe, call waiting was also introduced in the 1970s with the introduction of the first digital switching systems such as the EricssonAXE, Alcatel E10 and System 12. It was also available on some Ericsson crossbar exchanges, such as the ARE11 which, while electromechanical, was also computerised. Other digital systems such as the UK's System X also supported the service. Switching systems developed in the 1980s such as the German Siemens/BoschEWSD also had call waiting.
