Planning Automatic Route Selection And Toll Restriction; Direct Line Access; 3-Way Calling/Conference Service - Talkswitch CT.TS005.003902 User Manual

• Carrier codes can include numbers 0–9, "*" (asterisk), "#" (pound), ","
(comma for 2-second pause), and "w" (for wait-for-dial-tone). A 2-
second pause is automatically added after dialing a carrier code.
An entry in the ARS table can have one or two carrier codes. Carrier Code 1 is
either used all day, or from Start Time 1 until Start Time 2. Carrier Code 2 is
used from Start Time 2 until Start Time 1.
Use of Carrier Selection Prefix and Carrier Codes may require subscription to a
carrier's discount calling plan. This service may not be available in some
countries and on some telephone companies' telephone lines. Carrier
Selection Prefix may not be required if a "Pre-Selection" service is provided
by the telephone line service provider.

Planning automatic route selection and toll restriction

1. Identify the leading digits of calls to be blocked by toll restriction.
2. Identify the leading digits of calls to be routed by ARS.
3. Identify which telephone lines and VoIP lines are connected to different
service providers.
4. Assign telephone lines and VoIP lines to line hunt groups, in order to
provide separate access to each different service provider.
5. Identify carrier codes, which leading digits they work with, and when
they will be used.
6. Provide local extensions with access to line hunt groups. This controls
how local extensions have calls routed by ARS or blocked by toll
restriction.

Direct line access

When Direct Line Access is enabled on a local extension, the user does not
have to dial a line hunt group number. Calls placed from that local extension
are automatically routed to a designated line hunt group. If ARS is enabled
on the designated line hunt group, the calls are subject to ARS and toll
restriction.

3-Way Calling/Conference service

The use of the telephone company's 3-Way Calling/Conference service is not
recommended on telephone lines when ARS or toll restriction are used. The
system's ARS and toll restriction features do not have any control over the
routing of calls through these telephone company services.
