Hello,<br>
<br>
after a quick look over the code, I haven't spotted any issue.<br>
<br>
Do you call the function for the sip request or for sip reply?<br>
<br>
Can you attach the ngrep of the sip message you test for? I can use
it to test locally, re-injecting with protoshoot.<br>
<br>
Cheers,<br>
Daniel<br>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I want to check whether a parameter exists

<p class="MsoNormal">To be specific, I need to check if the
“received” parameter exists in the top most via header and
this is how I do it. The statements inside the if block get
executed all the time irrespective of whether the received

I doing wrong here?<o:p></o:p></p>
