Please note that no matter how each line is configured on the idle screen, all the lines in call screen will
keep line or shared line displayed for the corresponding accounts. For example, even if the user has
configured all lines as VPK (with non-LINE mode), he/she can still use the configured account to dial
out by Offhook or pressing SPEAKER, HEADSET or any other unconfigured LINE key to go to call
