A headset for a Cisco IP Phone 7960 would be nice but those headset are expensive. A home made-one is sufficient for your need. There is a good tutorial available to do it. I do not need a connection box, I just want to attach the headset to the phone.
- A headset with 3.5 mm connectors
- RJ-10 connector 4-pin/4-pin
- 3 heat shrink tubes
- some tools (Soldering gun, )
- 10 min
Now plug the headset in your headset jack and you are ready to go. The headset for 8 CHF (6$) wins no beauty contest. The author of this description makes no warranty of any kind. Use at your own risk.
