There is a feature in the SMAT number service known as ONE NUMBER DIAL. This service enables a subscriber to program several numbers from different networks or a combination of networks to be masked behind a SMAT Number such that a call to that SMAT Number automatically hunts and selects an available number from the various phone lines programmed therein.
It eliminates the frustration felt when people try to reach an organization through any of its several phone lines which might either be busy, out of network coverage, temporarily out of service etc. Companies have been known to lose patronage through negative reputation of having phone lines that cannot be accessed easily.
It allows many people to dial simultaneously and get through depending on the number of lines. It is convenient because it is recall friendly. It saves the time and trouble dialing individual numbers from the subscriber’s call list. It saves the prospective caller the frustration of dialing several numbers.
