Basic Call Features
101
3. User on phone A walks to an available conference room where the phone is
designated as phone C. The user dials call park retrieve code to retrieve the parked
call.
The system establishes call between phone C and B.
Note
You can use call pickup to answer someone else’s incoming call on your phone. The
SIP-T28P IP phone supports directed call pickup and group call pickup. Directed call
pickup is used for picking up a call that is ringing at a target phone number. Group call
pickup is used for picking up a call that is ringing at any phone number in a certain
group. The pickup group should be predefined, contact your system administrator for
more information.
You can pick up an incoming call by using the DPickup/GPickup soft key. To use call
pickup, you need to configure the call pickup code beforehand on a global or per-line
basis via web user interface.
Note
Directed Call Pickup
To enable the directed call pickup via web user interface:
1. Click on Features->Call Pickup.
The call park code and call park retrieve code are predefined on the system server.
Contact your system administrator for more information.
If the parked call is not retrieved within a period of time assigned by the system, the
phone performing call park will receive a call back.
If there are many incoming calls at the same time, pressing the GPickup soft key on the
phone will pick up the call that rings first.
The directed call pickup code and group call pickup code are predefined on the system
server. Contact your system administrator for more information.
The call pickup code configured on a per-line basis takes precedence over that
configured on a global basis.
