The Call Rerouting Assignment Table assigns Call Rerouting alternatives to each directory number in the
SX-2000. Each directory number is always assigned a First Alternative and a Call Rerouting Second
Alternative. Assignment of Call Rerouting Always Alternatives is optional, but each directory number may
use different Always Alternative for Day, Night 1, and Night 2 operation. The Call Rerouting Assignment
Table also assigns the type of Do Not Disturb to be used for each directory number. Do Not Disturb may be
selected for internal calls only, for external calls only, or for all calls, including calls from an attendant.
Calls reroute to an alternative answer point immediately if the preferred answer point is busy or in DND,
but Call Rerouting on ring-no-answer is governed by two timers. The Call Forward No Answer Timer, an
SX-2000 COS option, determines how long a call will ring at the called extension before rerouting to the
First Alternative answer point. The Call Rerouting Timer, an SX-2000 system option, determines the
maximum duration from the start of the call before the call reroutes to the Second Alternative answer
point.
The Call Rerouting Timer should be set longer than the longest value used for the Call Forward No
Answer Timer, but shorter than the sum of any two values for the Call Forward No Answer timer. This
gives the Call Rerouting First Alternative answer point time to answer an RNA-forwarded call before the
call reroutes to the Second Alternative answer point, and ensures that the call will reroute to the Second
Alternative answer point before it can forward elsewhere from the First Alternative answer point.
Call Rerouting is the recommended means for Octel 200/300 call coverage using CPI since it is defined
centrally in the PBX configuration and its operation is transparent to the individual using the extension.
Call Rerouting provides flexibility in assigning Octel 200/300 call coverage. This feature should be
applied carefully. Some questions to ask when specifying Call Rerouting that includes Octel 200/300 are
Under what calling conditions (e.g., busy, DND, RNA) should calls be forwarded to Octel 200/300?
-
Which type of Call Rerouting alternative should be used to forward calls to the Octel 200/300?
-
Call Rerouting Example.
Here is an example of how Call Rerouting may be specified to include the Octel 200/300. Figure 10.3-1
through Figure 10.3-4 show the Call Rerouting form entries for this example. The coverage conditions
are
Reroute internal calls and TIE trunk calls to coverage if station is RNA.
-
Reroute CO and DID trunk calls to coverage if station is busy or RNA.
-
Reroute all CO and DID trunk calls to the Octel 200/300 during Night 1 service, and all calls to the
-
attendant during Night 2 service.
Apply Do Not Disturb to all types of incoming calls.
-
Rerouting alternative answer points are
The First Alternative answer point is the Octel 200/300.
-
The Second Alternative answer point, in the event the Octel 200/300 fails to answer the call, is the
-
attendant.
