Caller ID
Caller ID is a feature
of automatic identification of the caller's number. As soon as the phone receives an incoming call, this feature will immediately show the caller's number on the display, allowing the user to know who is calling even before he accepts the call. But at the same time, there is one nuance that many people omit: when you request a number from the PBX, the phone immediately establishes a connection, that is, from the same minute, the billing of the call begins for the subscriber at the other end of the wire.
Display
The presence of the
display improves the usability of the phone. On the one hand, it is much more convenient to dial the desired number on such a device, since all numbers are displayed on the screen, which reduces the possibility of error. Also using the phone book feature is more convenient if there is a screen. On the other hand, the automatic number identification feature simply cannot be implemented on a phone without a display.
Amount of numbers in memory
The maximum amount of phone numbers that a user can store in the phone's memory. To make a call to one of these numbers, you do not need to remember complex combinations of numbers, just select the desired contact and press the call button. Usually, the numbers that you have to use most often are stored in memory: numbers of family members, friends, etc.
Speakerphone
Hands-free mode allows you to have a conversation with the person on the other end of the wire, without picking up the phone for this and not looking up from other activities. For this, a speaker and a microphone built directly into the phone case are used.
Wall mounting
The design of these phones provides the possibility of vertical
mounting of the device on the wall. Usually, models of this type are more compact in size, have a long cord, and in some cases also have keys on the handset.
