Trunk
Services
This parameter lets you configure the trunk group for the
outbound services described below. Unless specified, if an
option is not enabled, the trunk group does not provide that
service.
• Local—Select this check box to enable local calls.
• Long Distance—Select this check box to enable long-
distance calls.
• National Mobile (not shown)— This check box only
appears for PRI trunks in countries with “caller pays”
billing plans (e.g. Ireland). Select this check box to allow
users to call mobile numbers. Clear the checkbox if you do
not want to incur the associated costs of allowing users to
call mobile phones in “caller pays” environments.
• International—Select this check box to enable
international calls.
• n11 (e.g., 411 or 611, but not 911, which is specified
below)—Select this check box to enable telephone service
calls, such as directory assistance.
• 911—Select this check box to enable emergency 911 calls.
NOTE You must have at least one trunk group per site that
allows 911 calls.
• Easy Recognizable Codes (ERC) (e.g., 800, 888, 900)—
Click this check box to enable services such as toll-free
dialing.
• Explicit Carrier Selection (e.g., 1010xxx)—Click this
check box to enable dialing special numbers that let the
caller select a long-distance carrier.
• Operator Assisted (e.g., 0+)—Click this check box to
enable the trunk group to dial the operator.
• Called ID not blocked by default—Click this check box
to pass Caller ID information by default on outbound calls.
To block all calls, clear this option. Note that in the United
States, the user can override this option with Vertical
Service Codes.
