Use headset with Speedphone - so it'll work

If you want to make calls with your headset via your Speedphone, this is not possible with every model. We'll show you how it's done.

Connect the headset to the Speedphone and use it

• You can usually use any headset with a 3.5 mm jack on your Speedphone. However, professional telephone headsets often have a 2.5 mm jack. However, the problem can be solved with a 2.5 to 3.5 adapter.
• Like many headphones, the Speedphone uses the CTIA standard. This determines how the various contacts on the jack are assigned. Headsets, however, often use the OMTP standard. You then need an OMTP to CITA adapter for this.

In the next practical tip, we will show you how to extend the battery life of the Speedphone.
