Any user who is connected using the name ADMIN_USER and password ADMIN_PASSWORD, as defined in the configuration file, can invoke registered procedures directly through OpenSwitch’s built-in RPC parser. OpenSwitch attempts to capture all language commands and parse them as if they were RPC calls.
RPC calls executed in this fashion must be formatted like this:
[EXEC[UTE]] rp_name [value[, value...]]
Where:
rp_name – is the registered procedure to be executed
value – is the value of the parameter
You cannot pass parameters by name.
