[OpenSIPS-Users] function with 6 parameters

[Razvan Crainea]

Hello Bogdan,

I implemented a similar test function that takes 6 parameters.
All values seems to be in the correct order in both fixup function and 
triggered function.

I attached a small patch that prints the value of the parameters right 
after the fixup function and then again before the function is called.

Please apply this patch and then check if the parameters values and 
order match between the fixup and triggered function?

Regards,
Razvan
