Call Rerouting
Objectives
When you finish this module, you will:
Know the difference between call rerouting and call forwarding.
Program call handling for Call Rerouting Always.
Program call handling for Call Rerouting First Alternative.
Program call handling for Call Rerouting Second Alternative.
Understand how several sets can share alternative answer points.
Provide alternate answer points for devices that are unanswered.
Unanswered Call Handling
The 3300 ICP provides users with effective ways to ensure their calls are answered. If a called set is busy or fails to answer, the system can reroute the call to an alternate set. If the alternate set is busy or fails to answer, the system can reroute the call to a second alternate set.
Call Rerouting and Call Forwarding
There are two ways to control where calls reroute when they are unanswered:
•
Call Forwarding - programmed and activated from the set, users can specify which phone they wish incoming calls to go to. Calls can be forwarded to different phones based on:| External or internal call
| A busy phone or an unanswered phone
| Nothing; Calls are forwarded no matter what.
•
Call Rerouting - programmed in the system database, users cannot control the call rerouting of their phone. This ensures that even when the user has not forwarded their phone, calls to the set will follow the call rerouting path and be answered at the alternative answer points. Call forwarding overrides call rerouting.Since the number a call can be forwarded to may be different than the number that same call can be rerouted to, an order of precedence is required. The system treats the calls with this precedence:
1. Call Forward – Always 2. Call Reroute – Always
3. Call Forward – Busy/DND and/or No Answer 4. Call Reroute – Busy/DND and/or No Answer
Call Rerouting - Always
The system can reroute all calls to an alternate answer point. For example, you may wish to reroute DID calls arriving at a set 1003 to an alternate answer point 1100 after normal business hours. Call rerouting - always means that regardless of the condition of 1003, the calls ring at 1100.
There are four sources of a call to a set:
•
DID Trunks•
TIE Trunks•
CO Trunks•
Internal SetsYou may select all, or any subset of these, to reroute always. The calling source(s) you want to reroute are selected in the Call Rerouting Always Alternatives form. Program Reroute to devices you wish to reroute, and No Reroute to devices you do not wish to reroute. Rerouting can be set to happen when the system is in Day, Night1, and/or Night2 service. Here is an example.

Call Rerouting First Alternative
First and Second Alternative Rerouting depend on the condition of the set receiving the call. You can independently reroute the four calling device types depending on whether the called set is:
•
Idle•
Busy•
Not answering.First and Second Alternative rerouting do not depend on the Day/Night1/Night2 operating modes like Call Rerouting – Always does.
Called Set Is Idle
In the example below, when 1003 is idle, you might want both trunk calls and internal calls to ring the idle set and then reroute to 1200. If 1003 fails to answer, the system reroutes the call to 1200.
Called Set Is Busy
When 1003 is busy or in Do Not Disturb, you might want its trunk calls to reroute to 1200, but not the internal calls. This would allow internal callers to camp on or send callback messages to 1003, while trunk calls are answered at 1200.
First Alternative Rerouting Example
Devices Rerouted When Busy Rerouted When Idle / No Answer

TIE Trunks X X
CO Trunks X X
Internal Sets X
•
Normal = Do not reroute this device type•
This = Reroute this device type to the designated DN.•
Last = Reroute this device type to the Second Alternative’s designated DN.First Alternative Number 2 applies to 1003.
DID, TIE, and CO trunk calls will reroute to 1200 if 1003 is busy or in DND. Internal calls receive normal busy tone. All calls to 1003 reroute to 1200 when 1003 is idle
Call Rerouting Second Alternative
If the first alternative, set 2010, does not answer, you can reroute the call to a second
alternative, such as voice mail at 3050. You can independently enable rerouting to the second alternative for each of the four calling device types.
The example reroutes all trunk calls, but no internal calls, to the second alternative 3050. Leaving internal calls as Normal for the second alternative means they will not reroute to the second alternative. If the target set is idle and unanswered, the calls will remain ringing at the first alternative.

is busy, in DND, or doesn’t answer and if 1200 doesn’t answer. Internal calls receive
Sharing Alternative Answer Points
Once the Always, first, and second alternatives are defined, they can be applied to other phones. In this example of sets sharing rerouting patterns, they are applied to sets other than 1003.

Step Task Expected Result 9
7 Call the target set from the calling set, but do not answer it.
The call should ring on the target set, then route to the first alternate
destination set, then to the second alternate destination set.
8 Place the target set into DND. The target set is in DND. 9 Call the target set from the calling set. The call should ring on the first
alternate destination set, and if not answered, route to the second alternate destination set. 10 Place the first alternate destination set into
DND.
The first alternate destination set is in DND.
11 Call the target set from the calling set. The call should ring on the second alternate destination set.
Call Rerouting Timers
When the target set and the first alternative set are busy, the call reroutes immediately to the second alternative set. Timers are not required to limit the ringing duration since none of the sets ring.
When the target set and the alternative sets are ringing but not answered, timers control how long the call rings at each set before rerouting to the next alternative set.
The call rings at the target set for the duration of the Call Forward No Answer Timer. In the following example, this timer is in 1003’s COS. Its default value is 15 seconds. When the 15 seconds is up, the call stops ringing at 1003 and begins ringing the first alternative set 1200. The call rings at 1200 until the Call Rerouting Timer (CRR) or the Answer Plus System Reroute Timer (A+SR) expires.
The Call Rerouting Timer is in the System Options form and the Answer Plus System Reroute Timer is in the target set’s COS.
If the A+SR timer has any value greater than 0, the system uses it in place of the Call Rerouting Timer. The default values are A+SR = 0 and CRR = 22 seconds.
Note
The A+SR timer is only available if ACD Agent licenses have been purchased.
Note
These timers start counting when the target set begins ringing rather than when the first alternative set begins ringing. They must extend from the beginning of the target set’s ringing to the end of alternative set’s ringing. When the CRR or A+SR timer expires, the first alternative stops ringing and the second alternative starts ringing.
If an Attendant Console or other station originally transferred a trunk call to the target set, and if the final alternative fails to answer, the call returns to the Attendant Console or station that made the transfer.
Before returning to the console or station, the call rings at the last alternative for the duration of the No Answer Recall Timer (NART). The NART is in the incoming trunk’s COS. Its default is 17 seconds, and only applies to incoming trunk calls.
The following diagram illustrates the timer interdependencies. When the NART expires, the call is returned to the
transferring device.

Call Rerouting Path
The rerouting first and second alternatives are only those programmed against the initial
destination set. They do not include rerouting first and second alternatives programmed against other sets in the rerouting chain, such as against 1200 and 1250 in the example. But the call will go to the Always Rerouting alternatives belonging to the first and second alternatives.
