After provisioning, when you place a call and the callee is temporarily unavailable to answer the call, the phone
screen will prompt whether to wait for the callee party. You can activate the call completion feature. After the called
party becomes idle, the phone screen will prompt whether to dial the number.
Call Park and Retrieve
Call park allows users to park a call on a special extension and then retrieve it from another phone (for example, a
phone in another office or conference room).
The phones support call park feature under the following modes:
l
FAC mode: parks the call to the local extension or the desired extension through dialing the park code.
l
Transfer mode: parks the call to the shared parking lot through performing a blind transfer. For some servers,
the system will return a specific call park retrieve number (park retrieve code) from which the call can be
retrieved after parking successfully.
