After provisioning, you can easily press the Group Pickup key (line key 1) to pick up an incoming call to any phone
within a predefined group of phones.
Note: If the “linekey.X.value” is not assigned with a group pickup code, the Park key will invoke the group pickup code set by
“features.pickup.group_pickup_code” or ”account.X.group_pickup_code”.
Example: Setting a Line Key as Forward Key
When the phone receives an incoming call, you can press a Forward key to forward the incoming call to the preset
number.
