By default, Extension 700 is used to park calls.
- While in a conversation, press '#' to initiate a transfer, then dial '700' (e.g. '#700').
- You will hear a voice telling you the extension at which the call was parked (most likely '701' or '702'). Now hang up. The caller will be left on hold at the announced extension.
- On a different phone, dial the announced extension (e.g. '701'), and call the parked party
