The Multi-Link SR-3 is the simplest and most accurate distinctive ring only line sharing technology in the world today. It offers no programming or options except to choose either 2 or 3 numbers.

The SR-3 simply routes your calls to whatever phone devices you plug into it by the phone number (normal or distinctive ring) called. With the SR-3 you can have 2 or 3 phone numbers and pay for only a single line plus the small extra expense for the distinctive ring service from your phone company.  

The SR-3 will only work for incoming calls if you subscribe to your local phone company’s “distinctive ring service.” It can also be used without subscribing to distinctive ring service for only one incoming device (regular phone number) and up to two outgoing only devices such as modems or credit card terminals.

The reason it is always 100% accurate is that it uses Multi-Link’s patented “Smartware” technology that actually learns the ringing patterns from your particular local phone company’s “distinctive ring” service so can never make a mistake.

If configured properly with your local phone company it will work with phone company voice mail and call forwarding which are restrictions when using the more common tone detection products that don’t require the distinctive ring option from your phone company.

The only restriction is caller-id for the main (normal ring) phone number which will still work with an alternative installation using a simple single line two device adaptor. With this installation you would loose the barge-in protection with busy signal and all your phone calls would ring on a fax or modem call until the device answers.

If your only requirement is to route calls by distinctive ring, The SR-3 is a very good choice
