NS700 Stop second call ringing if already on a call

[Windy Miller]

Hi Guys, I have an extension that is a member of an ICD group. When they are already on a call, if another call comes in to the group, their phone still rings. Can I stop the phone ringing if they are already on a call? This applies to group calls, not a direct call.

Thanks

Turn off call waiting on the extension should stop a second call ringing the phone
