limit user to dial certain number. The rules below explain the judgment.
1.System will check the dialing plan on last page in advance to decide whether it is PSTN call or SIP call.
2.If the call will be send to SIP Proxy, then system will exams the number to see if it meets Rewriting Rule.
3.If the SIP call does not meets any Rewriting Rule, system will build the SIP call with the number that user dials.
4.If the numbers of the SIP call meets any Rewriting Rule, then the numbers is converted (or limited if it meets barring rule) and system build the SIP call by converted number.
Here is the example
Web Folder: ADVANCED \ DIALING PLAN
Pattern: Add the pattern that user may dial
Rewrite: Add the converted number if user dials the same digits in pattern column. Fill in digits and click the AddDialin button
By the operation above, we create a Rewriting Rule table below and it controls all SIP call.
| Pattern | Rewrite | X means any digits. ! means the call is terminated. | |
|

|
| If the prefix number dials from user are 001~009, then | |
| 00x |
| the 3 digits are removed. For example, if user dials | |
|
| 0028621123456, then the system dials 86211123456 to | ||
|
|
| ||
|
|
| build SIP call. | |
|
|
|
|
|
|
|
| If the prefix number dials from user are 0, then the digit | |
| 0 | 886 | is replaced with 886. For example, if user dials | |
| 0921123456, then the system dials 886921123456 to | |||
|
|
| ||
|
|
| build SIP call. | |
