ARS Selector Settings
•Selector
This must be a number in the range 65 to 99. Selectors 65, 66 and 67 are default entries that cannot be removed. The selector number is used in the Dial Numbers table to associate the ARS with external dialing prefixes that can use it. It can also be used as a line appearance button to allow users to specifically select the ARS group for an outgoing call.
•65: Group of Lines
This ARS selector cannot be deleted. By default it contains all analog lines in the system when the system was installed or defaulted. However, it can be edited to change the lines included including adding non-analog lines. This selector and 66 below are used as the default for all classes of external call.
•66: ISDN Standard Call - Local Number = Default
This ARS selector cannot be deleted. Calls routed to this selector will use an available ISDN trunk channel with the calling party information set to match the user's User Calling Line Identity if set or otherwise blank (to be set by the trunk provider). This selector and 65 above are used as the default for all classes of external call.
•67: ISDN Number Withheld - Local Number = Withheld
This ARS selector cannot be deleted. Calls routed to this selector will use an available ISDN trunk channel with the calling party information set to withheld.
•Type
The ARS Selector group can be used for the following functions:
•Group of Lines
This type of selector is used to create a group of lines. The lines are selected using the Select Lines table below. For a call routed to this selector, an available line from that group is used.
•ISDN Local Number
This type of selector is used to set an outgoing local number on an ISDN call. For a call routed to this ARS selector, an available ISDN channel is used with the calling party element of the Q.931 setup set to match the local number specified.
•Changing the calling party number may not be supported by the line provider or may be an additional chargeable service. It will also be subject to restrictions on what numbers can be used. It is normally a requirement that the calling party number used must be a valid number for return calls to the same trunk. Use of an invalid number may cause the call to be dropped or the number to be replaced by a default value.
•The default ARS Selector entry 66 is set to Local number=default. It uses the user's User CLI if set.
•ISDN Standard Call
This type of selector is used to select an available ISDN channel for the call.
•ISDN Number Withheld
This type of selector is used to withhold any outgoing local number information on an ISDN call. For a call routed to this ARS selector, an available ISDN channel is used with the calling party element of the Q.931 setup set to withheld.
•SIP Call-by-Call
These entries appear when entries are created in a SIP trunk's Call-by-Call table. They cannot be edited through the ARS Selectors form. By having an associated ARS Selector number, the entry can be selected as the destination for specific out going calls.
•Details
This field show either the lines currently selected for use with the ARS selector or the local number setting for the calling party number.
