  The SR-3 call processor is a passive line-sharing device that routes incoming phone (POTS) calls based on the “selective ring” service from the local telephone company. The SR-3 differs from the rest of Multi-Link’s line sharing switches that actively answer and route calls. The bottom line is the same—the main benefit is reducing phone lines and the monthly cost. Because the SR-3 routes in this manner, it can be used with common telco call packages that offer voice mail, call forwarding, and TTY/TTD. The SR-3 routes up to three numbers per line. The selective ring service goes by different names depending on the phone service provider, and this service must be activated for the SR-3 to route properly. Typical cost for a selective ring phone number is $5 per month. The SR-3 works on a standard POTS line and does not go “off hook” to screen but routes to the appropriate port based on the signature ring pattern for each phone number assigned to a single phone line. The primary phone number routes to port one, secondary number to port two, etc. Multi-Link’s “Smartware™” technology eliminates any user programming by automatically learning the ring cadence. Operation is totally automatic. The barge-in protection feature is optional. Outbound calls are processed in the normal fashion. For SOHO applications, the SR-3 allows a phone and fax machine to share a single phone line while using different numbers. One phone line can be used for home and business, with automatic routing. Only home phones will ring when the home phone number is called, and business calls are directed to the business phone or fax. Two Year Warranty. |
