Example Group Call Pickup Configuration
The following illustration shows you how to enable the group call pickup feature in the features.cfg
template.
When you enable the group call pickup, the phone will display a Pickup soft key when you go off-hook. If
you select Pickup, the Group soft key is displayed.
After you press the Group soft key, the phone performs a just-in-time subscription request to the fixed
address <groupcallpickup@<yourCallServerDomain> for dialog details with which it can pick up
the original caller using a replaces header in a new INVITE.
Configure Call Park and Retrieve
This feature is available as Open SIP. If you want to use the Call Park feature available with Lync Server,
see Feature Profile 84538. You can park an active call and retrieve parked calls from any phone.
Whereas call hold keeps the held call on the same line, call park moves the call to a separate address
where the call can be retrieved by any phone. This feature requires support from a SIP server and setup
of this feature depends on the SIP server. For example, while some SIP servers implement group call
pick-up using a particular star-code sequence, others implement the feature using network signaling. See
the table Configure Call Park and Retrieve for parameters you can configure.
