TALKSWITCH CONFIGURATION 35
2.3.3.7 Automatic Route Selection and Toll Restriction
Automatic Route Selection (ARS) allows outgoing calls to be redirected to
different telephone lines or VoIP trunks and hence network operators based
on the leading digits dialed to access geographical areas, mobile operators or
services. For example, use this feature to block all long distance calls or
redirect long distance calls to VoIP.
Toll Restriction allows calls to be blocked based on the geographical area
code, mobile operator, service number or access code dialed.
The comparison is based on finding the maximum number of leading digits
that match. If a match is found the call follows the action specified in the
ARS table. The action can be to block the call with an announcement or
re-route it to an alternative Line Hunt Group. The Line Hunt Groups are
setup to direct calls to specific telephone lines or VoIP trunks connected to
different network service operators. If there are no matching entries in the
ARS table, the call proceeds without any redirection or restriction to the Line
Hunt Group whose access code was originally dialed by the caller or specified
for direct line access.
Planning Automatic Route Selection and Toll Restriction
• Identify the leading digits of the numbers for the calls to be routed or
blocked.
• Identify which telephone lines and VoIP trunks are connected to
different networks and services.
• Identify which extensions’ calls you wish to route or block.
Configure Line Hunt Groups (also, see section 2.3.3.6)
Ensure that the Line Hunt Groups are configured.
In the TalkSwitch Configuration software, click System Information ->
Line Hunt Groups. We recommend that each network service provider’s
telephone lines or VoIP trunks are assigned to a separate line hunt group.
The Automatic Route Selection (ARS) table is programmed by the system
administrator with the leading digits of calls to be re-routed or blocked.
TalkSwitch routes outgoing calls through Line Hunt Groups to telephone
lines or VoIP trunks, dialing the outgoing Line Hunt Group access codes “9”
or “81” to “88” or directly when Direct Line access is enabled on an
extension. When ARS is activated for any Line Hunt Group and the caller
has dialed, their dialed digits are compared to the leading digit entries in
the Automatic Route Selection (ARS) table.
