What is the difference between line sharing products which route inbound calls by using tone recognition and those which route inbound calls by ring pattern recognition?
Units which use tones for inbound call routing use DTMF or CNG tones to determine the desired device destination and must “answer” the ring from the telephone company before they can hear and act on the tones. DTMF tones are like those created by a tone capable telephone. Units which route inbound calls based on “ring pattern” are generically using a process called Distinctive Ring Recognition”. These units Do Not “answer” the telephone company ring, but instead count the ring bursts within the ring interval, i.e. single, double or triple ring pattern. They then route the call to the applicable device associated with the ring pattern, for example, a double ring would be directed to the 2nd device port. These units require additional phone number(s) service be provided by the phone company to ring on the same line. Since the unit does not answer the call, it allows compatibility with phone company services that are dependent upon an un-answered scenario, such as Voice Mail or Call Forwa
