[OpenSIPS-Users] Evaluate script variable before calling module function

[Liviu Chircu]

Hello Douglas,

If you want the parameter to be a pseudo-variable only, you should:
- parse the '$...' string in the fixup phase with pv_parse_spec(...)
- get the spec value at runtime with pv_get_spec_value(...)

If you want the parameter to be either string or pv, you should:
- parse the string at fixup with the generic fixup_sgp(...) function
- get the generic parameter value at runtime with fixup_get_svalue(...) 
function
