I have 3 RCA telephones that allow up to 4 lines to be plugged in. No need for a super expensive phone system when RCA has your solution. $250 for all 3 phones.
RCA included all of the function that you need in your Small/Home Office in this business phone! This CW/CID* phone with IrDA port will handle up to four separate phone lines (each with distinctive rings and line-in-use indicators) and is expandable up to 16 separate stations. Enjoy hands-free dialing and auto-transfer to the handset with the full-performance speakerphone. The large, easy-to-read LCD display provides quick reference for the clock time and day, number dialed, memory verification, call timer and memo. For added versatility, the data port provides connection for a fax, modem or answerer with line selector and you can add an optional cordless handset (H5400RE3 separately available).
