ARS Selectors

ARS selectors are used to create groups of available lines. These can then be specified as the groups of line to be used for different types of external calls in the Dial Numbers Table. An available trunk in an ARS selector group can seized by dialing 8 followed by the ARS selector group number or using a line appearance button configured for the ARS selector group number.

•ARS Selector Table
This table is used to edit and add ARS selectors. A selector number can be dialed to seize a matching line by dialing 8XX where XX is the selector number required. Selector numbers can also be assigned to line appearances to make outgoing calls.

•Selector
This must be a number in the range 65 to 99. Selectors 65, 66 and 67 are used by default entries.

•65: Group of Lines
This entry cannot be deleted. By default it contains all analog lines in the system, however it can be edited to change the lines included.

•66: ISDN Standard Call - Local Number = Default
This entry cannot be deleted. Calls routed to this entry will use an available ISDN line with the calling party information set to match the user's User CLI if set or otherwise blank (to be set by the provider).

•67: ISDN Number Withheld - Local Number = Withheld
This entry cannot be deleted. Calls routed to this entry will use an available ISDN line 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.

•Select Lines
This table is used to add or remove lines from the currently selected ARS selector if its Type is set to Group of Lines.
