To park a call:

BLIND TRANSFER BUTTON followed by *00 to 09 to specify the parking orbit.

For example *01 will place the call in the parking orbit 1.

*02 will place the call in the parking orbit 2 etc.

To pick up a parked call:

*10 to 19 where the 0 – 9 is the park orbit number

For example *11 will pick up any calls parked in parking orbit 1

*12 will pick up any calls parked in parking orbit 2

Multiple calls in parking lots

Parking lots support parking of multiple calls. Therefore, when un-parking, you can add the extension number from which the call was parked to be sure that you un-park the particular call you had initially parked there.

For example, if extension 100 parked a call in park 0, this call can be picked up by extension 101 by keying in *10100
