MOS Score
A MOS or Mean Opinion Score is a number that is a measurement of how a human judges the quality of an experience or an event. A common application of this is the star-ratings review.
Modem
A modem is a device that converts both digital signals to analog and also analog signals to digital. Modems send data over the telephone network by converting signals that can be transmitted and then converted back at the other end. They are a crucial bridge from digital to analog and vice versa.
Messaging
Messaging is storing or forwarding messages by voice mail, fax, or broadcast. The primary method is to store the recording for later playback. This can be traditional voicemail, visual voicemail, or another method.
Multi-Line Phone
Multi-line phones allow landline systems to handle multiple calls at once with dedicated buttons that correspond to different phone lines. VoIP systems generally do not use multi-line phones because VoIP’s hosted functions and superior tech make most routing automatic or user-guided.
