Description
The Cortelco Trendline (815047-VOE-21F) is a full-featured single-line corded telephone in eye-catching Cherry Red — the same dependable Trendline platform with a high-visibility finish that's perfect for designated emergency, courtesy, or hotline phones where the set needs to stand out. It includes a lighted keypad, hi/lo/off electronic ringer, last-number redial, flash, and mute, and it's hearing aid compatible with a 12-foot coil cord.
The Telecom Spot Take
The Cherry Red Trendline earns its place wherever a phone needs to be found fast: courtesy phones in lobbies, designated help or hotline sets, and safety stations where a bright, obvious handset matters. It's the same simple, rugged Trendline underneath — lighted keypad, adjustable ringer, redial, flash, and mute — just in a color that signals "use me." It's tone/pulse switchable and hearing aid compatible for universal line and user compatibility. For everyday neutral installs, the Black or Ash Trendline is the standard choice.
