Enhanced reorigination
Enhanced reorigination allows a user to originate and complete multiple
calls successively. To access enhanced reorigination, the user presses the
octothorpe (#). Enhanced reorigination uses a combination of dual tone
multiple frequency (DTMF) receivers and special tone receivers (STR) to
ensure proper detection of the octothorpe. STR hardware is not presently
supported on the ISDN DTCI. Reorigination occurs with DTMF receivers
only.
Originating agencies
Enhanced reorigination is available for calls that access VNET services via
dedicated access agencies that connect user equipment directly to the
DMS-250 switch. Enhanced reorigination is conditionally available for
dedicated access calls with the following originating agencies:
Datafill in TRKGRP
VNET calls on PRI agencies that allow reorigination are based on the
settings in table TRKGRP of the VNREORIG (VNET reorigination)
parameter.
ISA defines the process of giving call-by-call access to public and private
network services through one common ISA facility, as shown in Figure 7-3.
