Configuration Exception
There are specific instances in incoming Request-URI messages where the Oracle® Enterprise Session Border Controller ignores specific parameters and automatically adds header-rules.
In a Request-URI, all parameters are URI parameters, and URI headers are not allowed. If you define values for the “allow-header-param”, “allow-uri-header-name”, and “allow-uri-param”, the Oracle® Enterprise Session Border Controller ignores these parameters in the Request-URI. Instead the Oracle® Enterprise Session Border Controller automatically adds header-rules for incoming “Via”, “From”, To”, “Call-ID”, and “CSeq” messages. These are explicit header rules and cannot be deleted. Each header-rule in a Request-URI has parameters populated with the value of *. If required, a user can change the header-rule parameter values with the values identified in the following table.
| Header Rule | Applicable Parameter | Required Value(s) |
|---|---|---|
| Via | allow-header-param |
|
| From | allow-header-param |
|
| To | allow-header-param |
|
| Call-ID | allow-header-param | No restrictions |
| CSeq | allow-header-param | No restrictions |
