Add Alternate Route

Navigation: System Settings > Alternate Route Selection > Add/Edit Alternate Route

Click Add/Edit Alternate Route to open the Create Alternate Route page where you can provision a location. When you click Add/Edit Alternate Route, you are prompted to specify a server.

Each ARS form contains short codes which are used to match the result of the short code that triggered use of the ARS form, ie. the Telephone Number resulting from the short code is used rather than the original number dialed by the user.

For Server Edition, this type of configuration record can be saved as a template and new records created from a template.

These settings are mergeable. Changes to these settings do not require a reboot of the system.

Field Description
ARS Route ID The default value is automatically assigned. Range = 0 to 99999.

For most deployments, do not edit this field.

For those conditions where it is necessary to edit this field, the value must be unique within ARS and within the line Outbound Group IDs.

Route Name Default = Blank. Range = Up to 15 characters.

The name is used for reference and is displayed in other areas when selecting which ARS to use.

Dial Delay Time Default = System. Range = 1 to 30 seconds.

This settings defines how long ARS should wait for further dialing digits before assuming that dialing is complete and looking for a short code match against the ARS form short codes. When set to System, the system's Dial Delay Time (System | Telephony | Telephony) value is used.

Secondary Dial Tone Defaults = Off.

When on, this setting instructs the system to play secondary dial tone to the user. The tone used is set by the field below.

The tone used is set as either System Tone (normal dial tone) or Network Tone (secondary dial tone). Both tone types are generated by the system in accordance with the system specific locale setting. Note that in some locales normal dial tone and secondary dial tone are the same.

When Secondary Dial Tone is selected, the ARS form will return tone until it receives digits with which it can begin short code matching. Those digits can be the result of user dialing or digits passed by the short code which invoked the ARS form. For example with the following system short codes:

In this example, the 9 is stripped from the dialed number and is not part of the telephone number passed to the ARS form. So in this case secondary dial tone is given until the user dials another digit or dialing times out.

  • Code: 9N

  • Telephone Number: N

  • Line Group ID: 50 Main

In this example, the dialed 9 is included in the telephone number passed to the ARS form. This will inhibit the use of secondary dial tone even if secondary dial tone is selected on the ARS form.

  • Code: 9N

  • Telephone Number: 9N

  • Line Group ID: 50 Main

Check User Call Barring Default = Off

If enabled, the dialing user's Outgoing Call Bar setting and any user short codes set to the function Barred are checked to see whether they are appropriate and should be used to bar the call.

Description Default = Blank. Maximum 31 characters.

Use this field to enter a description of this configuration.

In Service: Default = On

This field is used to indicate whether the ARS form is in or out of service. When out of service, calls are rerouted to the ARS form selected in the Out of Service Route field.

Short codes can be used to take an ARS form in and out of service. This is done using the short code features Disable ARS Form and Enable ARS Form and entering the ARS Route ID as the short code Telephone Number value.

Out of Service Route Default = None.

This is the alternate ARS form used to route calls when this ARS form is not in service.

Time Profile Default = None.

Use of a ARS form can be controlled by an associate time profile. Outside the hours defined within the time profile, calls are rerouted to an alternate ARS form specified in the Out of Hours Route drop-down. Note that the Time Profile field cannot be set until an Out of Hours Route is selected.

Out of Hours Route Default = None.

This is the alternate ARS form used to route calls outside the hours defined within the Time Profile selected above.

Short Codes Short codes within the ARS form are matched against the "Telephone Number" output by the short code that routed the call to ARS. The system then looks for another match using the short codes with the ARS form.

Only short codes using the following features are supported within ARS: Dial, Dial Emergency, Dial Speech, Dial 56K, Dial64K, Dial3K1, DialVideo, DialV110, DialV120 and Busy.

Multiple short codes with the same Code field can be entered so long as they have differing Telephone Number and or Line Group ID settings. In this case when a match occurs the system will use the first match that points to a route which is available.

Alternate Route Priority Default = 3. Range = 1 (low) to 5 (high).

If the routes specified by this form are not available and an Alternate Route has been specified, that route will be used if the users priority is equal to or higher than the value set here. User priority is set through the User | User form and by default is 5. If the users priority is lower than this value, the Alternate Route Wait Time is applied. This field is grayed out and not used if an ARS form has not been selected in the Alternate Route field.

If the caller's dialing matches a short code set to the Barred function, the call remains at that short code and is not escalated in any way.

Alternate Route Wait Time : Default = 30 seconds. Range = Off, 1 to 60 seconds.

If the routes specified by this form are not available and an Alternate Route has been specified, users with insufficient priority to use the alternate route immediately must wait for the period defined by this value. During the wait the user hears camp on tone. If during that period a route becomes available it is used. This field is grayed out and not used if an ARS form has not been selected in the Alternate Route field.

Alternate Route Default = None.

This field is used when the route or routes specified by the short codes are not available. The routes it specifies are checked in addition to those in this ARS form and the first route to become available is used.

Cause Codes and ARS

ARS routing to digital trunks can be affected by signalling from the trunk.

The following cause codes cause ARS to no longer target the line group (unless it is specified by an alternate ARS route). The response to cause codes received from the line is as follows.

Code Cause Code
1 Unallocated Number.
2 No route to specific transit network/(5ESS) Calling party off hold.
3 No route to destination./(5ESS) Calling party dropped while on hold.
4 Send special information tone/(NI-2) Vacant Code.
5 Misdialed trunk prefix.
8 Preemption/(NI-2) Prefix 0 dialed in error.
9 Preemption, cct reserved/ (NI-2) Prefix 1 dialed in error.
10 (NI-2) Prefix 1 not dialed.
11 (NI-2) Excessive digits received call proceeding.
22 Number Changed.
28 Invalid Format Number.
