Description
The Cortelco Business Series Two-Line Caller ID Telephone (122000-TP2-27S) brings two-line capability and caller ID with call waiting to Cortelco's reliable business desk phone. It's a capable, value-focused choice for front desks and small offices that handle two lines and want to see who's calling on each.
The Telecom Spot Take
For offices that have outgrown a single line but don't need a full digital system, this two-line caller ID phone hits the sweet spot. Staff can manage two lines, screen callers, and handle calls with familiar flash and redial controls — all on durable, modular Cortelco hardware. We recommend it for reception, dispatch, and owner desks that juggle two lines daily. Hearing aid compatible and tone/pulse switchable for any analog setup.
