DIAL PEER

This feature allows the user to create rules to make dialing easier. There are several different
options for dial rules. The examples below will show how this can be used.
Example 1: Substitution – Assume that it is desired to place a direct IP call to IP address
192.168.119. Using this feature, 156 can be substituted for 192.168.1.119.
Example 2: Substitution – To dial a long distance call to Beijing requires dialing area code
010 before the local phone number. Using this feature 1 can be substituted for 010. For
example, to call 62213123 would only require dialing 162213123 instead of 01062213123.
Example 3: Addition – Two examples are shown. In the first case, it is assumed that 0 must
be dialed before any 11 digit number beginning with 13. In the second case, it is assumed
that 0 must be dialed before any 11 digit number beginning with 135, 136, 137, 138, or 139.
Two different special characters are used.
x – Matches any single digit that is dialed.
[] – Specifies a range of numbers to be matched. It may be a range, a list of ranges separated
by commas, or a list of digits.
