# ARS Routes

## Purpose

The ARS Routes form assigns Trunk Group number, COR group, and Digit Modification Numbers to Route Numbers. It also specifies

- the routing medium (TDM, IP, SIP) that the route uses,

- the point in the output stream at which overlap outpulsing is to begin; and

- whether compression should be used over IP trunks.

The ARS Routes form is referenced by the ARS Digits Dialed, ARS Route Lists, and ARS Route Plans forms.

The ARS Routes form refers to the ARS Digit Modification Plans form and the Class of Restriction Groups form.

### Call Compression

IP Phones are usually grouped into zones by location. When a call is placed between phones residing in different zones on a MiVoice Business system, the call is compressed if possible to reduce bandwidth consumption.

When a call is placed between MiVoice Business systems, the route compression setting in the ARS Routes form determines whether the call should be compressed, if possible. If the set is in a different zone than MiVoice Business, however, compression is applied for the call is possible, even if Route Compression is "Off".

Starting with 3300 ICP Release 8.0, a few changes have occurred for call compression. The Compression Zone Assignment form is now called the Network Zones form. Compression zones are now referred to simply as "Zones". A call between different zones either on the same MiVoice Business system or on different systems results in a compressed call where possible. The Route Compression setting is now typically set to AUTO. This setting uses the zones of the originating and terminating devices to select compression, if appropriate. When connecting to other MiVoice Business systems running older software, this field should be set to ON or OFF. During an upgrade from a previous release, the existing settings are maintained, that is, ON or OFF. The Route Compression setting should be modified to enable the new behavior after confirming that the zone numbering between MiVoice Business systems doesn't conflict.

Use this form when performing the following tasks:

- Program Automatic Route Selection

- Advanced Automatic Route Selection Programming

## Field Descriptions

Parameter | Description | Default Value
Route Number | System-generated, protected field. A preprinted list of Route Numbers. The maximum number of Routes is: 200 (if the Maximum Elements per Cluster is 30 or 60) or 1200 (if the Maximum Elements per Cluster is 250 or 999). Route Numbers are referred to in the Termination entry of the ARS Digits Dialed form and the ARS Route Plans form. |
Routing Medium | Select the trunk medium the ARS Route will use. The Direct IP Route is used to provision IP trunks between MiVoice Business systems. Trunks seized via the Direct IP Route medium use Interconnect Restriction 65 and the same fixed trunk attributes at both the originating (local) and destination (remote) end. The attributes are as follows: Release Link Trunk is “No” Call Recognition Serivce is “Off” Class of Service is “100” Class of Restriction is “100” Baud Rate is “300” Intercept Number is “35” Non-dial In Trunks Answer Point(s) are all blank Dial In Trunks Incoming Digit Modification – Absorb is “0” Dial In Trunks Incoming Digit Modification – Insert is blank Trunk Label is blank The IP trunk calls originated via the “Direct IP Route” ARS routing medium default to use COR Group 65 and Digit Modification number 805. You can select different values, but typically should not have to. You can change COS 100 parameters, restrictions for COR Group 65, restrictions for Interconnect 65 and define intercept handling for Intercept 35. | Blank
Trunk Group Number | Enter the Trunk Group Number (programmed in the Trunk Groups form) to be used by the route. Does not apply to Direct IP Route. IP trunks seized for outgoing calls via the Direct IP Route medium use the following fixed IP/XNET Trunk Group attributes and behaviours: The destination MiVoice Business system is defined by the ARS route Maximum network hops is fixed at “26” Network Signaling Type and Network Voice Medium are fixed to “IP” Number of trunks per trunk group is unlimited. | Blank
SIP Peer Profile | Use the pull-down box to select a previously provisioned SIP Peer Profile for this route. | Blank
PBX Number / Cluster Element ID | Applies to Direct IP Routes only. Specify a destination MiVoice Business system for calls taking this route by entering the PBX number/CEID of the MiVoice Business system. The number must match an entry in the ICP/PBX Networking form. | Blank
COR Group Number | Enter the COR Group Number (Class of Restriction Groups form). The COR Group Number specifies the Classes of Restriction that do not have access to the route. NOTE: For XNET, ensure that the COR group does not contain the COR of the PRI trunk. | 1 or 65 for trunks using Direct IP Route
Digit Modification Number | Enter the appropriate Digit Modification Number (see the ARS Digit Modification Plans form). | 1 or 805 for trunks using Direct IP Route
Digits Before Outpulsing | Select a value in the range of "1" to "25" digits, in increments of 1. This value indicates at which point in the processing of external numbers overlap outpulsing is to begin. This is an optional field. It may be left blank if no overlap outpulsing is required. When this field is left blank, the digits are sent out as "Enbloc". When using Digit Outpulsing with Forced Non-verified Account Codes, this field must be left blank if the Route Type is set to "Non-Verified Account". | Blank
Route Type | Select "Emergency" from the drop-down menu to designate a route as an emergency route. CAUTION: Do not route non-emergency calls through a route designated as an emergency route. Any call routed to a trunk designated as an emergency route will generate a local emergency call notification and associated logs. No call to the PSAP See Public Safety Answering Point. is placed. Select "Non-verified Account" to designate a route to require a Forced Non-verified Account Code. Select "PSTN Access Via DPNSS" to designate a DPNSS route used for PSTN access. | Blank
Compression | Select "On", "Off "or "Auto" to indicate if compression should be applied over IP trunks. "Auto" indicates that the system chooses the compression codec based on the network-wide zone configuration. Compression for IP trunks using the Direct IP Route medium is fixed to "Auto." | Off/Auto
