Hi Andrei,

thank you for providing this. I found working with a bunch of function 
parametern is much more natural then providing different "avp_foo" variables 
that are used in other modules as a workaround. Where one should check for a 
valid number of parameters  when this VAR_PARAM_NO is used? In the fixup 
function, or the function implementation?

Cheers,

Henning
