The hold option specifies hold permissions for this trunk. If set to “Open”, any station
can place this trunk on hold and any other station is allowed to retrieve the call. If set
to “Private”, only the station that places the call on hold can retrieve the call.

If enabled, a polarity reversal will be marked as received when an outgoing call is
answered by the remote party. For some countries, a polarity reversal is used for
signaling the disconnection of a phone line and the call will be considered as “Hangup”

Hangup activity. The default setting is 8000.
