Helpful tips for setting common fields
The procedures in this section cover the specific fields you must administer when 
you create each type of trunk group. Here are some tips for working with common 
fields that are available for most trunk groups.

 in this field allows users to route calls through an 
outgoing or two-way trunk group by dialing its trunk access code.

SECURITY ALERT:
Calls dialed with a trunk access code over Wide Area 
Telecommunications Service (WATS) trunks are not validated against 
the ARS Digit Analysis Table, so users can dial anything they wish. 
For security, you may want to leave the field set to 
n
 unless you need 
dial access to test the trunk group.
Which phone numbers are associated 
with each trunk group?
For incoming or two-way trunk groups:

use to call into your switch over this group?
What’s the destination extension to which 
this trunk group delivers calls? Does it 
terminate at an attendant or a voice-mail 
system?
For outgoing trunk groups:
What extensions can call out over this trunk 
group?
Is the service from your network 
service provider sending digits on 
incoming calls?
Direct Inward Dial and Direct Inward/Outward

Are you inserting any digits? What are they?
Are you absorbing any digits? How many?
What range of numbers has your service 
provider assigned you?
