1.24 Portable Station (PS) Features
224 Feature Guide
• When the PS ring group is called using the floating extension number, the group becomes
busy to other callers using the floating extension number. However, the individual group
members may be called directly using their extension number.
• If a PS in a PS ring group has set the DND feature for trunk calls, the PS will not ring when
an intercom call or a trunk call arrives at the PS ring group. ( 1.3.1.3 Do Not Disturb
(DND))
• For calls directed to PS ring groups, the PBX will handle at most two calls simultaneously.
The third call cannot arrive at a PS ring group until one of the first two calls is answered or
a caller hangs up.
