2nd listener

Is it possible to have a second handset or headset on one phone to use for training purposes?

Re: 2nd listener

Hi Rod,

If you use Plantronics Headsets there is a "Y" cord made specifically for this purpose.

"Y" Training Adapter

The Y training cable allows you to connect two headsets with QD (Quick Disconnect) connections to one phone. It also includes a mute switch which allows you to mute either headset.

This adapter is compatible with the following products:

QD amplifiers, such as the M12, M10, M22, MX10, M12 LUCM, A20, and S20

Polaris headsets

DA series adapters (for USB ports)

Avaya/Lucent HIC and HIP cables

It is not compatible with the S12 or any cordless/wireless products. (A CA10 with a 2.5mm to QD adapter cable is the only exception.)

The part number for the Y training adapter is 27019-03.

There are 2 versions of the Y training adapter. The difference is the version of the QD locks in the package.

27019-03 has 62976-01 - Latest version of the Quick Disconnect (QD) lock

27019-01 had 29733-01 - Older version of QD lock

If you have an older style of QD connection (which has a flat edge rather than a semi-circle at the end), the Y cord for those versions of QD has been obsolete and is no longer available. They were part number 21847-01 (for SSI) and 21847-02 (Supra) and they also did not have a mute switch.

Hope this helps!
