Call waiting has practically become a requirement for home and business phone lines. You will rarely hear a busy signal when making a call today. Even if the recipient of your phone call is talking to someone else, your call will be connected to them.
Call Waiting Qualities
With call waiting, you can receive calls during a separate phone conversation. By pressing the flash button on your phone, you can switch over to the next call. Of course, you will have to put the original caller on hold when you make the switch.
Receiving multiple calls has been made easier with the invention of caller ID. Caller ID allows you to see who is calling your phone, or at least the telephone number. Therefore, if you are on the phone with one person, and another call comes in, you will be able to see who is on the other line with caller ID.
Call waiting can be used on any type of phone. It is common and appreciated for household phones. For cell phones and business lines, it is considered a necessity.
