Multiappearance Conference/ Transfer
DCS Multiappearance Conference/Transfer provides transparency for transferring
calls and conferencing calls within a DCS network. A user in the DCS can initiate
conference calls among or transfer calls originated from extensions in the DCS
network to another extension within the DCS by dialing the UDP extension. (For
transferred calls, the destination need not be within the DCS.)
In a DCS, if a party in a conference hangs up or completes a transfer leaving only
outgoing trunks on the call, the system attempts to preserve the connection if any
of the remaining parties on the call is a DCS tie trunk.
Trunk Group Busy/Warning
Indication
DCS Trunk Group Busy/Warning Indication provides attendants with a visual
indication that the number of busy trunks in a remote group reached an
administered level. A visual indication is also provided when all trunks in a trunk
group are busy.
Note: DCS Trunk Group Busy/Warning Indication is not available if you
are using DCS over ISDN-PRI.
To use this feature, you must have a DCS Trunk Group between the local and
remote switches, and the trunks in that trunk group cannot insert digits on
incoming calls. If you need digit insertion on these trunks, it should be added on
the outgoing trunk based on the dialed digits.
Except for System 75, System 85, and DEFINITY G2 switches, you can
administer DCS Trunk Group Busy/Warning Indication only for remote trunk
groups that are directly connected to the local switch. Trunk group access codes
for these trunk groups must be 3 digits or less and cannot include trunk members
100 through 999.
DCS with Rerouting
DCS with Rerouting allows a call’s connection between two DEFINITY systems
to be replaced by a new connection. All of the trunks used in the original path
must be DCS and the new path utilizes only DCS trunks. DCS with Rerouting
provides the following capabilities:
~ Attempts to obtain a better (generally less expensive) connection.
~ May replace the current path of a call with a route that is better in terms of
Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) routing
preferences administered on a DEFINITY ECS.
~ Frees up resources being used unnecessarily.
DCS with Rerouting primarily provides you with the ability to attempt to be more
effective with the usage of Trunk groups administered for Supplementary Services
Protocol Option E (SSE) during the existence of an active call. This means using a
more preferred route (in terms of UDP/AAR/ARS routing preferences
administered on the PBX) between the PBXs involved.
Your users invoke DCS with Rerouting by Call Transfer, Transfer out of Audix,
and dial 0 out of Audix. DCS with Rerouting must be enabled on a switch-wide
basis and the trunk groups involved must be administered as SSE.
