How to turn off call waiting on a 5602 DECT Phone

[propes]

I have a Dec phone and would like to turn off call waiting does anyone have any ideas.

This is on a Mitel system rel: 9.0.1.17

Many thanks in advance

I think the COS for the phone will need to be changed. Look specifically at the auto camp on timer and blank it.

The phone would need a Multi Call programmed under the second button to have full features available.
In 4.2 there is an option that says: Force busy if any line in use. This togetter with Auto Campon empty should fix your issue.
