Refurbished Microphones for Conference Phones
An expansion microphone is a wired add-on microphone that plugs into a conference phone so it can pick up voices across a larger table or room. These refurbished microphones are made for specific conference phones and older video conferencing systems.
The range covers Polycom SoundStation 2, SoundStation IP 7000, CX3000 and ViewStation microphones, Cisco 7936 and 7937 external microphones, Avaya B100 series and 4690 microphone kits, and Konftel expansion microphones. They suit offices that want to extend a conference phone they already own. For a complete unit, see Conference Phones.

How to choose an expansion microphone
Match the phone model
An expansion microphone only works with the conference phone family it was made for. Each product title names that phone, such as the Polycom SoundStation IP 7000 or Cisco 7937. Check the model label on the base of your phone before you order.
Check your phone has ports
Some conference phones have no socket for extra microphones. For example, the Polycom SoundStation 2 takes expansion microphones only in its EX version. Look for microphone ports on the back or side of your unit.
Count the microphones you need
Most phones in this range accept up to two expansion microphones. Each one extends pick-up so people at the far end of a long table are heard clearly. Some products are sold singly and some as a kit, so read the title.
Know the cable and connector
Expansion microphones use the phone maker's own cable and connector, and they only plug into the phone. For a microphone you can use with a computer, look at a USB speakerphone or a USB headset.

Questions
What refurbished microphones do you sell?
We sell refurbished expansion microphones for conference phones and older video conferencing systems. They come from Polycom, Cisco, Avaya and Konftel, and each one fits a named phone model. The product title tells you which phone it is made for.
Do you sell refurbished USB, XLR or wireless microphones?
Mostly not, because this range is built around expansion microphones for conference phones. These plug into the phone with the maker's own cable. For calls from a computer, a USB speakerphone gives you a microphone and speaker in one USB device.
Will any expansion microphone fit my conference phone?
No, each expansion microphone fits only the phone family it was made for. Makers use different connectors, and some phones have no microphone ports at all. Match the phone model in the product title to the label on your unit, or ask us to confirm.
How many expansion microphones can I add to a conference phone?
Most phones in this range take up to two expansion microphones. The exact number depends on the model, and some listings are a kit while others are a single microphone. Check your phone's user guide, or send us the model before you order.
