Replacement for the ComSwitch 350

The ComShare 350 is discontinued. The perfect replacement is Line Routing Switch 4.1.

LineShare 4.1- LineShare 4.1 ™ is the best new line sharing technology in the world today. This is perfect replacement for any Command Communications products. Almost every function that any switch that Commmand Communications ever made is included in this product plus more. Caller-id, Call waiting, and almost all of the phone company features are standard.

More information and more specific products are avaliable at faxswitch.com.

ComShare 350 was a single line unit with 3 ports (3 linked + 1 individual).  This was a passive unit meaning it did not answer the incoming call.  It monitored the telephone line and if the FAX CNG tone or DTMF transfer codes were detected, the call was routed accordingly. 

Due to the nature of its operation, the Answering Machine/Phone port would ring on every incoming call and Caller ID was received by the connected devices.  Every phone on the line would ring and receive Caller ID.  The Line Routing Switch 4.1 is the closest LRS replacement – user needs to configure for the home mode of operation.
