Call Pickup
You can use call pickup to answer someone else’s incoming call on your phone. The SIP-T48S 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 DPickup/GPickup. To use call pickup, you need to
configure the call pickup code beforehand on a global or per-line basis via web user interface.
The call pickup code configured on a per-line basis takes precedence over that configured on a
global basis.
Note
If there are many incoming calls at the same time, tapping GPickup on the phone will pick up the
call that rings first.
For some servers, the system will return a specific call park retrieve number (park retrieve
code) from which the call can be retrieved after parking successfully.
