If you want to enjoy listening to your business desk phone binaurally with your hearing aid telecoils, you can do so now with the CLA7V2 neckloop. If your desk phone does not have a 2.5mm headset jack, you will need to use an amplifier that connects to the phone.
You'll need the Vista amplifier with this special cord for the CLA7V2 neckloop. This cord allows you to plug in the CLA7V2 and then connects to the Plantronics Vista M22 amplifier. Each must be purchased separately.
One end of the connector cord has a 3.5mm jack and the other end has an RJ9 plug that connects to the M22 Vista amplifier.
