Least Cost Router LCR403 for Voice, Fax, and Data with automatic Dialer Functionality

The ISDN Router LCR403 is inserted in the ISDN line between the PBX and the PSTN. A PRI line to an alternative carrier network or Corporate Network is connected to the third port. The LCR403 compares the dialed information to the previously defined LCR table. If the called number is in the table, then the call is routed to the carrier/corporate network. If the called number is not in the table, then the call is routed to the PSTN.

Since the dialing functionality is identical to that of the ADC401, the LCR403 can also be utilized as a Dialer to select alternative carriers.

Like all the other Least Cost Routers by Sonic Telecom, the LCR403 features "Call Blocking" functionality as well as the possibility to admit carrier access codes for pre-selection.
