Dial Patterns of Outbound Route
Dial Patterns of Outbound Route
This topic describes dial pattern settings of Outbound Route to help you understand and configure the dial patterns of Outbound Route.
Match Pattern
A pattern specifies routing rules to route a call based on the digits dialed by a user. The PBX matches a dial pattern and routes the call out based on the dial pattern.
| Pattern | Description |
| X | Refers to any digit between 0 and 9. |
| Z | Refers to any digit between 1 and 9. |
| N | Refers to any digit between 2 and 9. |
| [1237-9] | Refers to any digit in the brackets, example [123] would match the numbers 1, 2, or 3. Range of numbers can be specified with a dash, example [136-8] would match the numbers 1, 3, 6, 7, and 8. |
| . | Wildcard . matches one or more numbers. Example 9011. matches any numbers starting with 9011 (excluding 9011 itself). |
Prepend
Prepend is an optional setting. The prepend will be added to the beginning of a successful match. If the dialed number matches the Pattern, the prepend will be added to the beginning of the number before placing the call.
Example:
If a trunk requires 10-digit dialing, but users are more comfortable with 7-digit dialing, you can prepend a 3-digit area code to all 7-digit phone numbers before the calls are placed.
Prefix
You need to configure Prefix according to the dial pattern settings on your outbound route. If the Prefix is not configured correctly, the PBX cannot call to the external number successfully.
- Leave Prefix setting blank
If you don’t have to add a prefix before the phone number.
As the following figure shows, only the destination number that starts with digit 6 can be called out through this outbound route.
For example, to call number 6287361, you should dial the number 6287361 directly.
- Add prefix before a number
As the following figure shows, to make calls through the outbound route, you need to add prefix 9 before the number, and the destination number should start with digit 6.
For example, to call number 6287361, you should add prefix 9 before the number 6287361.
- CallerID
If CallerID is supplied, the dialed number will only match the prefix + match pattern. if the CallerID being transmitted matches this. When extensions make outbound calls, the CallerID will be their extension number and NOT their Outbound CID. The above special matching sequences can be used for CallerID matching similar to other number matches.
