Desk conferencing for analog lines

The Polycom VoiceStation 300 is a voice conferencing device built for analog PBX or public switched telephone connections. It suits small meeting rooms or home offices that rely on traditional phone wiring rather than VoIP infrastructure. Three sensitive microphones provide 360-degree coverage up to 7 ft. pickup range. The unit is new and ready for immediate deployment.

Microphone reach and speaker limits

Gated microphones with intelligent mixing and Dynamic Noise Reduction keep conversations clear within the stated 7 ft. radius and 300-3500 Hz microphone response. The speakerphone outputs up to 86 dBA SPL at 0.5 m across 300-3300 Hz, which is adequate for quiet rooms but will not fill larger spaces. No digital or IP interfaces are present, so integration with modern UC platforms requires additional adapters.

Analog-only connectivity decides fit

The single decisive specification is the analog line interface: one data port and one audio line-out connect directly to a legacy PBX or PSTN line. Buyers who need SIP, USB, Bluetooth or Ethernet integration cannot use this device without external gateways. The 19-key keypad handles on-hook, off-hook, flash, redial, mute, hold and volume controls locally.

Questions about this item

Will the 360-degree microphone pickup still cover my meeting table if I keep using the same analog PBX line?

Yes — the three gated microphones with intelligent mixing provide 360-degree room coverage up to 7 ft. while the device connects through its analog PBX or public switched telephone interface.

How can I confirm the IEEE 1329 Type 1 full-duplex audio is active after I plug in the external power adapter?

Place a call and verify that both parties speak and hear each other simultaneously without clipping; the 86 dBA SPL peak volume at 0.5 m and 300-3300 Hz speaker response indicate the full-duplex path is working.

Does the box include the external power adapter and the cable for the data port, or do I need to order them separately?

The unit ships with the external power adapter; the 1 x data port and 1 x audio line out connections use standard cables that are not included and must be sourced separately.
