VVX 600 IdleViewPreferenceRemoteCalls

 I'm running UC 5.5.1.11526 on a VVX 600. I'm trying to uliize the following setting.

up.IdleViewPreferenceRemoteCalls="1"


Use this parameter to determine when the phone displays the idle browser.
When set to 1, a phone with only remote calls active, for example, on a BLF monitored line, is treated as in the
active state and the idle browser does not display.
When set to 0, a phone with only remote calls active, for example, on a BLF monitored line, is treated as in the idle
state and the idle browser displays.

This does not seem to work. If a monitored line is ringing or in use the phone stays at idle and still shows the idle browser.
