[OpenSIPS-Users] Max Forward Header Function

[Faisal Rehman]

Hi Everybody,

I have a very tiny & crazy question but it is confusing me & I couldn't find its accurate answer over google that why we use "!"this before mf_process_maxfwd_header function in the main routing block. I have also seen this symbol with other functions like!is_method("REGISTER|MESSAGE") so what's its soul purpose?

How can I test the functionality of just the mf_process_maxfwd_headerfunction?

 
Regards,

Faisal Rehman
