Conference Call - Toshiba IP edge General Description Manual

The Class of Service consists of four specific parameters:
• Class of Service (COS) is used to check if a station or port is entitled to access a feature.
• Destination Restriction Level (DRL) is used by the Toll Restriction feature to check if the
calling party is allowed to make a call to the dialed external destination.
• Facility Restriction Level (FRL) is used by the Station CO Line Access to check if the calling
party is entitled to access the trunk facility.
• Queuing Priority Level (QPL) is used by the Automatic Callback feature and the Off Hook
Camp On feature to determine the queuing priority of the calling party.
COS is used to check if a station or port is entitled to access the feature. DRL is used by
the Toll Restriction feature to check if the calling party is allowed to make a call to the
dialed external destination. FRL is used by the Station CO Line Access feature to check if
the calling party is entitled to access the trunk facility. QPL is used by the Automatic Call-
back feature and the Off-hook Camp On feature to determine the queuing priority of the
calling party.
The COS is always referred against the configuration table, while the DRL/FRL/QPL are
referred with their numeric values. Thus, the numeric value of COS is just an index. In
addition to the COS index, the station profile may be used to represent more detailed and
complex information of allowance/denial of stations. As for the DRL/FRL/QPL, the larger
value has higher priority than the smaller value. The COS takes indexes 1 through 32
while DRL/FRL/QPL take levels 1 through 16.

Conference Call

The Conference Call feature enables a user to establish a conversation with two or more
parties. These additional parties may be internal or external to the IPedge system. Any
IP5000 Series telephone may establish a conference call with other stations or outside
lines.
Some models of SIP telephones, including the Toshiba IP4100 Series, also have their own
built-in conference feature. Please refer to the device documentation for description and
programming instructions.
A conference is defined as three or more parties joining into one conversation. A maxi-
mum of eight parties are allowed into a conference with up to six from outside lines or
eight parties on internal stations.
The originator of the first conference is the "conference master" and controls the adding
and dropping of conference parties. The conference master may drop the last added party
