System
System response to an incoming DID call (analogue CO line):
1. set-up a connection based on the defined Start signal,
2. collect incoming digits based on the programmed Receive Digit Count,
3. handle digits based on the Conversion type (0-2),
4. route the call to assigned destination.
System response to an incoming DID call (ISDN line):
1. set-up a connection based on the received call set-up messages,
2. collect incoming digits and delete digits from left based on the programmed ISDN Remove
Digit Count,
3. handle digits based on the Conversion type (0-2),
4. route the call to assigned destination.
Conditions
1. If ICLID routing is assigned for the CO/IP Line, the received Caller Id is compared to the
ICLID Table for routing first. If Caller Id does not match an entry in the ICLID Table, the
normal DID call processes are used.
2. DID calls that encounter a busy signal, are not answered in the DID/DISA No Answer Timer,
or are received at a vacant or invalid number can be routed to the Attendant, a tone, Station
group, or VMIM/VSF announcement. When the Attendant receives such calls, the call is
appropriately identified by the Attendant iPECS Phone display.
3. For a station that is part of a non-pilot Station Hunt group, DID calls will follow the group hunt
process if the Station is busy or does not answer the call.
4. DID calls are subject to Group Call Pick-up and Directed Call Pick-up.
5. If a VMIM/VSF announcement is defined as the destination in the Flexible DID Destination
Table, a Caller Controlled Routing Table for the announcement can be defined. iPECS can
be configured to drop (disconnect) the call after playing the recorded announcement.
