The following topics provide information about HMR syntax and variables.
HMR Syntax
HMR Syntax is available in the following format:
| Code Block |
|---|
Header_Value | Condition?Header_Value_1:Header_Value_2 | Condition?Header_Value_1 |
The Condition format can only contain accepted variables.
If Condition returns a non-blank value, the system will take Header_Value_1 as the header value. If the Condition value returns blank (no value), the system will take Header_Value_2.
When the Header_Value_2 is not configured, the system will not append the header to the outgoing SIP messages.
You can enter the Header_Value as a concatenation of Segments using the "+" sign.
| Code Block |
|---|
segment + segment + segment + ... |
Each Segment can be any of the values described in the following table.
| Caption |
|---|
|
| Segment | Description |
|---|
| Literal | A string literal that needs to be copied verbatim into the resulting header value. The string literal should be enclosed in single quotes. Example: 'sip:' | | Variable | One of the pre-defined variables. Variables extract a value from the received SIP message or the environment and place it into the value. Variables are preceded by a '$' sign. Example: $from.uri.user | | User Variable | One of the pre-defined user variables. User variables extract a value from the client's URI in the client information and place it into the value. User variables are preceded by a '$' sign. Example: $userinfo.contact.parameter[param_name] | | Function | Functions operate on the variables and insert the result into the value. Example: replace($diversion, '88', '408') |

| From | $from.dispname | Display name. | | $from.uri.user | User name portion of the URI. | | $from.uri.host | Host portion of the URI. | | $from.uri.port | Port from the URI. | | $from.uri.parameter[user] | Value of the URI Parameter 'user'. | | $from.uri.header[h1] | Value of the URI header 'h1'. | | $from.parameter | Value of the From parameter 'tag'. | | To | Same as From. | | Contact | Same as From. | | Route | Same as From. | | Record-Route | Same as From. | | P-Asserted-Identity (PAI) | Same as From (use $pai instead of $from). | | P-Preferred-Identity (PPF) | Same as From (use $ppf instead of $from). | | Via | $via.ip.host | Value of sent-by. | | $via.ip.port | Value of sent-by port. | | $via.parameter[branch] | Value of parameter 'branch'. | | Request URI | $request.method | SIP method. | | $request.uri.user | Request-URI user. | | $request.uri.host | Request-URI host. | | $request.uri.port | Request-URI port. | | Other Headers | $diversion.text | Extract the entire diversion header from the received message. |
