564 Conference
When a switchhook flash transfers calls on analog (500/2500 type)
telephones with three-party conference (C6A) Class of Service, the
transferring party goes on hook, leaving the other two parties established.
Telephones with a C6A Class of Service involved in a conference having
more than three parties must add the last party to the conference, then flash
the switchhook and go on hook to complete the transfer.

Called Party Disconnect Control

Trunks with Called Party Disconnect Control allowed are treated as trunks
without disconnect supervision when conferenced.
Calling Party Name Display Denied
Call Party Name Display, and thus the Calling Party Name Display Denied
enhancement, do not apply to conference calls.
Calling Party Privacy
The Calling Party Privacy (CPP) feature will pass the Privacy Indicator to the
terminating set to inhibit the display of the Calling Party Name and Number
if the Conference feature is used for the purpose of performing a transfer.

Camp-On, Forced

Telephones involved in Conference calls cannot be camped on to. Overflow
tone is returned to telephones attempting Forced Camp-On.

Centrex Switchhook Flash

Centrex Switchhook Flash (THF) allows conference calls through the CO. It
can be invoked only if there is an established call connected to an outside
trunk. If the telephone is engaged in internal conference calls, THF cannot
be used.

Charge Account and Calling Party Name

Conference calls produce multiple Call Detail Recording (CDR) records.
Whenever a new trunk is added to a conference, the connection between
the connected telephone and the trunk is recorded, and a connection to the
conference loop is established. This causes CDR to generate a start record
with the telephone and trunk identified as the involved parties. As trunks are
removed from a conference, CDR end records are produced. These records
may identify different telephones or conferences as the local parties.
China - Attendant Monitor
If any party involved in a monitored call attempts to activate conference,
monitoring is immediately deactivated. With Attendant Monitor active, the
attendant cannot create a conference without first disabling the Attendant
Monitor feature.
