[SR-Users] search_hf returns always true

[Daniel-Constantin Mierla]

Hello,

after a quick look over the code, I haven't spotted any issue.

Do you call the function for the sip request or for sip reply?

Can you attach the ngrep of the sip message you test for? I can use it 
to test locally, re-injecting with protoshoot.

Cheers,
Daniel
