Sorting calls by distinctive ring patterns
When lines, telephones and Hunt groups are configured on
your system, they can be assigned one of four distinctive ring
patterns (DRP). The default for all telephones is 1 and the
default for lines and Hunt groups is None, which is the lowest
priority. The highest priority is 4.
Call ringing:
When multiple calls are presented to the
telephone, the call with the highest priority DRP setting will be
the call that rings at the telephone.
Call answering:
When multiple calls are presented to a
telephone, and the user picks up the handset, the call with the
highest priority DRP setting is the call that is presented.
Note: External calls always have a higher priority than
internal calls.
Note: If the ring type is changed on a telephone after the DRPs
are set on the line, the line DRPs are overwritten by the
telephone settings. If the DRPs are set for a line after
telephone programming, then the telephone ring
programming is overridden by the line DRP program.
Refer to the
Modular ICS 6.0 Installation Guide
for
information about setting distinctive ring for lines. If
the call is to a Hunt group, and the Hunt group DRP is
higher than the line DRP, the Hunt group DRP will take
precedence within the Hunt group. Refer to
Assigning a
distinctive ring pattern to a Hunt Group
