FAQs
A tonecaller is a loud external ringer designed to make incoming telephone calls easier to hear in noisy or large environments. They are commonly used in:
- Warehouses and workshops
- Server rooms and network operations areas
- Retail, schools, or public buildings
- Environments with low phone audibility
Tonecallers amplify the ring signal and can produce a high volume audible tone, making them ideal where a standard desk phone ringer is not sufficient.
Most tonecallers are compatible with analogue PSTN and PBX telephone lines, as they detect the ring voltage on the line. Before choosing, check:
- The line type (standard PSTN, PBX extension, or ATA for VoIP)
- The REN rating supported (Ringer Equivalence Number)
- Whether the tonecaller requires a separate power supply
Tonecallers generally work with business phones from ATL Telecom, BT, Interquartz, and most other analogue telephones.
Key features include:
- Adjustable volume is essential for noisy environments
- Tone variation, selectable high/low pitch options
- Wall or desk mounting depending on installation location
- Visual indicators, like flashing lights for extra alerting (useful in loud spaces)
- Low power consumption is ideal for continuous use
- REN rating compatibility ensures the tonecaller works alongside phones on the same line
Industrial grade tonecallers often provide very high dB output for maximum audibility.
Most tonecallers are easy to install and require only basic steps:
- Connect the tonecaller in parallel with the telephone line
- Mount the device on a wall or desk as needed
- Adjust volume and tone controls
- Connect a power supply if the device requires external power
No specialist tools are necessary, and installation typically takes just a few minutes.
