Ccr Groups; Direct Extension Dialing - Northern Telecom Compact ICS 4.0 Manual

CCR groups

CCR allows callers to reach groups of telephones by dialing a
single digit they select from the audio menu. You create the
CCR groups in programming.
When a call is sent to a CCR group in which all the telephones
have the same programming, the call goes to the telephone
with the lowest internal number.
If the telephones in a CCR group have different programming,
the call is handled by the telephone programming that takes
effect first. For example, if a telephone in a group forwards
after two rings, it forwards the call from CCR before the
telephones in the group that are programmed to forward after
three rings.
A CCR call is forwarded by Forward on Busy, the Call
Forward feature code, and Callback programming. Be sure to
keep this in mind when programming the telephones in your
CCR groups.
When a call that was handled by CCR rings at your telephone,
call information appears automatically on the display. You
must subscribe to a call display service and have the proper
equipment installed in your system for this feature to work. If
CCR is programmed to answer the call in less than two rings,
the call information may not be captured and forwarded to the
telephones in the CCR group.

Direct extension dialing

Both System Answer and CCR give the caller the opportunity
to dial an internal telephone number or use remote feature
access such as direct inward system access (DISA). This
means callers do not have to wait to reach the person they are
calling and only the person they are calling has to handle the
call.
