ISDN Setup Message Manipulation

ISDN Setup Message Manipulation allows you to match and modify elements of the setup message, specifically the Calling Number and Called Number IE (Information Element). You can select either the setup messages arriving from the ISDN side or setup messages being sent to the ISDN side. 

ISDN Setup Message Manipulation page is divided into four sections:

• Rule
• Match
• Modify
• Action

   ISDN Setup Message Manipulation Parameters

   Item	Description
   Rule The Rule section contains the global configuration for each rule.
   Rule Number	You can add multiple rules, and Rule Number is the key for each rule. The Rule Number can be any number between 1 and 9999. When parsing the rule list during a call, the EdgeMarc searches by the rule number in ascending numerical order. When a new rule is created, a rule number is automatically assigned. It is higher than the previous rule number. Note: This number cannot be modified when you are adding a new rule. You can edit the rule number to move it into a different order once you've created the rule. You can also not enter duplicate rule numbers.
   Direction	This is the direction in which the rule should be applied. Choose the direction from the drop-down list: Both ISDN -> SIP direction only SIP -> ISDN direction only
   Enabled	Allows the rule to be enabled/disabled without deleting the rule. It is 'enabled' by default.
   Match The Match section has all the fields available in the called and calling IE that can be selected to match. If more than 1 item is selected to match, a logical AND is used. If a logical OR is used, multiple rules can be added.
   Called Number The fields in this subsection concern the Called Number IE.
   Number	This field is used to match a complete or partial Called Number. The valid characters for this field are: 0-9 digits: Normal digits. '#': The '#' (hash) sign as a digit. '*': The '*' (asterisk) sign as a digit. Note: This is not used as a wildcard. '.': The '.' (period) character indicates that a digit must be present in its place and can be any digit. '+': The '+' (plus) character is used to indicate the presence of any number of digits to either the left or right of the match digit string. If a true substring is required, a '+' can be used on both sides of the same string. Note: The '+' character can only be used as the first or last character.
   TON	Type Of Number (TON) indicates the type of Called Number. The type of the Called Number can be any of the following: Unknown International National Network Subscriber Abbreviated
   NPI	Number Plan Identification (NPI) identifies the numbering plan if known. Choose the numbering plan from the drop-down list: Unknown ISDN Data Telex National Private
   Calling Number All fields in this subsection concern the Calling Number IE.
   IE State	This field matches and checks whether a Calling Number IE is present. Choose either of the following from the drop-down list: Present: The Calling Number IE must be present to match. Missing: The Calling Number IE must not be present to match. Note: If this option is selected, no other Calling Number IE parameters can be selected for matching.
   Number	This field is used to match a complete or partial calling number. The valid characters for this field are: 0-9 digits: Normal digits. '#': The '#' (hash) sign as a digit. '*': The '*' (asterisk) sign as a digit. Note: This is not used as a wildcard. '.': The '.' (period) character indicates that a digit must be present in its place and can be any digit. '+': The '+' (plus) character is used to indicate the presence of any number of digits to either the left or right of the match digit string. If a true substring is required, a '+' can be used on both sides of the same string. Note: The '+' character can only be used as the first or last character.
   Digit State	This field matches and checks whether the calling number is present in the Calling Number IE. For this to match, the Calling Number IE must be present. Choose either of the following from the drop-down list: Present: A Calling Number IE must be present to match. Missing: The Calling Number must not be present to match. Note: If this option is selected, the Number field in the Calling Number subsection will be unavailable.

   NPI	Number Plan Identification (NPI) identifies the numbering plan if known. Choose the numbering plan from the drop-down list: Unknown ISDN Data Telex National Private
   PI	Presentation Indication (PI) indicates whether or not the calling number should be displayed. Choose one of the following PI from the drop-down list: Allowed Restricted Not Available Missing
   SI	Screening Indication (SI) indicates whether the calling number is screened. Choose one of the following SI from the drop-down list: User, Not Screened User, Verified Passed User, Verified Failed Network Missing
   Modify The Modify section configures how the calling number and called number information will be modified. For each rule, the modify section is only used if the Match section returns a match.
   Called Number The fields in this subsection define how the called number IE will be modified, if at all. Note: A called number is mandatory for the call to proceed. Certain rule configurations can result in an empty called number field. If this occurs, the action is to reject the call.
   Action	Choose what action you want to take on the Called Number digit field: None: No action is taken on the called number digits with this selection. Strip All: This selection strips all digits in the called number digit field. Strip Selected: This selection strips the digits in the called number match field. For example, if the called number match is +123+, the matched location in the digit string has 123 stripped. Strip Count: This selection strips the count of digits in the Strip Count field. The strip occurs from the beginning of the field. For example, if the called number is 00123456, and the strip count is 3, then the resulting called number is 23456.
   Strip Count	This field indicates the number of digits to strip from the called number digits. Note: This field is active only if Action is set to Strip Count.
   Add Digits	Indicates the digits to be added to the called number digit field. Digits are added only after the digit stripping action is performed.
   Add Digits Position	Indicates the position to which the digits should be added. Choose either of the following from the drop-down list: Prefix Suffix

Strip All: This selection strips all digits in the calling number digit field. Strip Selected: This selection strips the digits in the calling number match field. For example, if the calling number match is +123+, the matched location in the digit string has 123 stripped. Strip Count: This selection strips the count of digits in the Strip Count field. The strip occurs from the beginning of the field. For example, if the calling number is 00123456, and the strip count is 3, then the resulting calling number is 23456. Remove IE: This selection removes the entire Calling Number IE.
   Strip Count	This field indicates the number of digits to strip from the calling number digits. Note: This field is active only if Action is set to Strip Count.
   Add Digits	Indicates the digits to be added to the calling number digit field. Digits are added only after the digit stripping action is performed.
   Add Digits Position	Indicates the position to which the digits should be added. Choose either of the following from the drop-down list: Prefix Suffix
   TON	Type Of Number (TON) indicates the type of Calling Number. The type of the Calling Number can be any of the following: Do Not Alter Unknown International National Network Subscriber Abbreviated
   NPI	Number Plan Identification (NPI) identifies the numbering plan if known. Choose the numbering plan from the drop-down list: Do Not Alter Unknown ISDN Data Telex National Private
   PI	Presentation Indication (PI) indicates whether or not the calling number should be displayed. This field modifies the PI to the value set. If Remove is selected, then Octet 3A is removed. The SI value is also set in Octet 3A, so if either the PI or SI is set to Remove, the other one is automatically set to Remove. Choose one of the following PI from the drop-down list: Allowed Restricted Not Available Remove
   SI	Screening Indication (SI) indicates whether the calling number is screened. This field modifies the SI to the value set. If Remove is selected, then Octet 3A is removed. The PI value is also set in Octet 3A, so if either the PI or SI is set to Remove, the other one is automatically set to Remove. Choose one of the following SI from the drop-down list: Do Not Alter User, Not Screened User, Verified Passed User, Verified Failed Network Remove
   Action The Action section contains general actions for the rule.
   Block Call	This field decides whether the rule sets the call to be blocked. This control takes effect only if the rule is matched. Choose either of the following from the drop-down list: Allow Call: This allows the call to proceed normally. This is the default setting. Block Call: This sets the call to be blocked or rejected. It works in tandem with Rule Check. If the call is marked as Blocked Call and Rule Check is set to Continue, the call continues to search for rules. If another Rule Match sets Block Call back to Allow Call, that action is used. If the Rule Check is set to Stop, the call is rejected because the rule search is complete.
   Rule Check	This field decides whether the search for matching rules continues or stops with the rule. The Rule Check option only applies if the Rule Matches. Choose either one of the following actions: Stop: This option stops the search for additional rules if the rule is a match. This is the default setting. Continue: This option allows the search for additional matching rules to continue. If a particular rule matches and has this option set, the new data to be used is the modified data by this rule. The next rule uses the modified data to match.
