Polycom Extension Mics VTX1000, IP6000, IP4000

Polycom Extension Mics – Expand Coverage for VTX1000, IP6000, IP4000 Conference Phones

The Polycom Extension Mics are essential add‑on accessories designed to boost the microphone pickup range of your Polycom VTX1000, IP6000, or IP4000 conference phone. In larger conference rooms or when participants are seated far from the main unit, these external microphones ensure every voice is picked up clearly. Each extension mic connects to the main phone via a dedicated RJ‑11 port and can be placed on the table to extend coverage up to several feet. With modular microphones, you can cover long tables, U‑shaped seating, or noisy environments without upgrading to a more expensive system.

How It Works

Each extension microphone plugs into the expansion mic port on the back of your Polycom conference phone using the included 7‑foot cable. The microphone unit sits flat on the table (often with a non‑slip base) and contains a high‑sensitivity, noise‑canceling element that picks up voices from up to 8‑10 feet away. The main phone automatically detects the external mic and adds its audio to the conference mix. Some models support daisy‑chaining or adding up to two extension mics. The result is seamless, natural conversation for everyone in the room, even those at the far ends. For a complete hands‑free meeting experience, pair your conference phone with high‑quality wireless headsets from FindHeadsets for private listening or roaming participants.

Compatibility & Design

These extension microphones are compatible with specific Polycom models: VTX1000, SoundStation IP6000, and SoundStation IP4000. They are also compatible with Polycom SoundStation 2W, 2W EX, and some VSX series (check your device). Each mic unit is approximately 3 inches in diameter and 1 inch tall, with a 7‑foot flat cable terminated in an RJ‑11 connector. The microphone element is omnidirectional or cardioid (depending on model). The base has a non‑slip rubber ring to keep it in place on polished tables. The package includes a single extension mic; multiple units may be used (some models support up to 2). The color is typically silver/grey or black to match the phone.

Why Choose This Product

Adding extension microphones is far more affordable than replacing an entire conference phone system. The VTX1000, IP6000, and IP4000 are still widely used in many boardrooms, and these mics restore and extend their capability. Without extension mics, participants more than 6 feet from the main unit may sound quiet or muffled. With them, you can cover rooms up to 20 feet long. The plug‑and‑play installation requires no special tools or configuration. For organizations with existing Polycom hardware, this is a smart, low‑cost upgrade to improve meeting equity for all.
