Short Code Matching Examples

The default dialing short codes for North American U-Law systems are a good example of the interactions within a set of short codes using several special characters.

The short codes are:

• • 9/./Secondary Dial Tone

  • [9]0N;/0N/Dial

  • [9]1N;/1N/Dial

  • [9]N;/N/Dial

  • [9]XXXXXXXXXX/XXXXXXXXXX/Dial

Explanation

• Short Code 1: 9/./Secondary Dial Tone
  This short code returns secondary dial tone immediately a user dials 9. This is a special short code as despite a match having occurred, the IP Office puts the digits back through short code matching again.

• Short Code 2: [9]0N;/0N/Dial
  This short code contains a number of special characters; [ ], N and ;.

• • The [9] allows this short code to be used as a follow on match to the previous 9 that triggered secondary dial tone.

  • The 0N matches any dialing following the 9 that begins with a 0.  

  • The ; tells the IP Office to use the dial delay timer expiring or the user dialing # to indicate that dialing is complete. That allows this short code to be used as an exact match even though there is also a possible match to the [9]XXXXXXXXXX short code.

  • In North America this short code is used for international calls.

• Short Code 3: [9]1N;/1N/Dial
  This short code is similar to short code 2 but is used for dialing that begins 91.

• • In North America it is used for national calls.  

• Short Code 4: [9]N;/N/Dial
  This short code is again similar to short codes 2 and 3. It matches any dialing that begins with a 9. However it is not used until the dial delay timer expires. When that occurs, a match to 90 (short code 2) or 91 (short code 3) is used as the more exact match.

• • In North America this short code is used for 7 digit local numbers.

• Short Code 5: [9]XXXXXXXXXX/XXXXXXXXXX/Dial
  This short code used X characters to match single digits, in this case up to 10.

• • This is a possible match to all dialing that begins with a 9. However the ; in the other possible matches allows them to be used when the dial delay timer expires or the user dials #.

  • If the user dials 9 and then continues dialing without allowing the inter-digit dial delay time to expire, as soon as they have dialed the 10 additional digits this short code is used.

  • In North America this short code is used for 10 digit local numbers.

Further Examples

The following examples are not meant as practical examples. However they are simple to implement and test on  real system without conflicting with its normal operation. They illustrate the interaction between different short codes in resolving which short code is an exact match. They assume that extension numbers are in the 200 to 299 range.

The term 'dials' means dialing the indicated digit or digits without the inter-digit Dial Delay Time expiring.

The term 'pause' means a wait that exceeds the inter-digit Dial Delay Time.
