<p class="MsoNormal"><span style="color:blue">Hi Liviu, <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">As I already emailed you, to contribute the source code there is some approval process in our organization.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">If that goes though I can contribute the REST PUT code.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">But I have a question in async operation in opensips.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">When a async mode REST API is called either POST/PUT, I see that opensips waits for 10 sec of time and then only it sends out the HTTP request out to the network.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">Why there is a huge wait time of 10sec?
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">When I tried to debug, I found it is looping inside the below for loop for long time in rest_methods.c file, (but all that looping are taking same seconds, later 10 sec am getting HTTP response)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">for (i = 0; i < busy_wait; i += check_time) {…..}<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:blue">Wondering and interested to know about this delay time.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:blue">Please bear some of your time</span><span style="font-family:Wingdings;color:blue">J</span><span style="color:blue">. Thanks in advance.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:blue">I have downloaded 2.1.4 version if opensips and trying to use rest_put call in async mode.

<p class="MsoNormal"><span style="color:blue"> </span><o:p></o:p></p>
<p class="MsoNormal"><span style="color:blue">I have added the necessary code for rest_put () similar to rest_post() in rest_methods.c, rest_methods.h and rest_client.c
