Buying Guide
What makes a good music on hold player? Reliability, compatibility with your phone system, and ease of updating MOH content are key factors. Consider outputs (8/600 ohm), whether you need a built-in monitor speaker, and if you require preloaded content or the ability to customize messages.
- System compatibility: Confirm that the MOH device supports your PBX, KSU, or landline configuration and has the correct analog outputs (RCA or 3.5 mm).
- Content management: Decide if you need preloaded music/messages or a device that accepts your own files via USB/SD.
- Audio controls: Look for models with volume and tone controls and a dedicated speech/music mode to optimize caller experience.
- Monitoring capabilities: A built-in monitor speaker helps verify audio quality without external equipment.
- Durability and operation: Choose industrial-grade devices for 24/7 operation and power-loss recovery features for uptime.
