VOPTech GoIP User Manual

This rule enables the GoIP to add 0 before the mobile phone number and 0755 before the

telephone number.

The above rule can be change to:

“0:|13[0-9]xxxxxxxx:+0|[1-8]xxxxxxx:+0755”

Similarly, this rule enables the GoIP to add 0 before the mobile phone number and 0755

before the telephone number. However, the length of the mobile phone number is limited

to 11 digits.

As shown above, the length of telephone numbers is limited to eight digits. 13[0-9]xxxxxxxx

and [1-8]xxxxxxx represent mobile phone numbers 130xxxxxxxx to 139xxxxxxxx, and

telephone number 1xxxxxxx to 8xxxxxxx, respectively.

Note: When the length of the number is specified, the exceeded numbers will be discarded if

the length of the number exceeds the specified length. For example:

The rule is “0:|13[0-9]xxxxxxxx:+0|[1-8]xxxxxxx:+0755”.

When you dial the number 88990011 and 8899001133, the result is the same. The number

actually dialed is 075588990011.
