T53W/T53/T43U/T27G, X=1-21; for T42U/T42G/T42S/T41P/T41S, X=1-15; for T40P/T40G/T23P/T23G, X=1-3; for

Example
######Set a Park key######
linekey.1.type = 10
linekey.1.value =4603
linekey.1.label =Bill
######Set a Retrieve key####
linekey.3.type = 56
linekey.3.line =1
linekey.3.value =4603
linekey.3.label =Retrieve Bill
After provisioning, you can easily press the Park key (line key 1) to park a call to a specific extension (4603) during
a call, and press the Retrieve key (line key 3) to retrieve the parked call from the specific extension (4603) when the
phone is idle.
If the “linekey.1.value” is set to blank, the park key will perform as the Park soft key.
Note: In FAC call park mode, the Park/Retrieve key invokes the call park code/park retrieve code by default. Therefore, the
phone dials out *684603 to park a call, and dials out *884603 to retrieve a call. If these codes are not set, you can assign code
and extension to “linekey.X.value”, for example, “*684603”.
Example: Set a Park/Retrieve Key for Transfer Call Park Mode
