Hi team, Any clue on this below topic would be a great. Am stuck with this 10 sec delay and couldn't move further. If I could be able to find the root cause and resolve this , then only I can implement REST API calls as async. Because this 10 sec delay is a huge time. Please help me on this.

As far as I debugged this delay is caused by curl library. But wondering what could be the cause for this constant 10.25 sec delay.? Please help me out in this.

If that goes though I can contribute the REST PUT code. But I have a question in async operation in opensips. 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. Why there is a huge wait time of 10sec? 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) for (i = 0; i < busy_wait; i += check_time) {.....} Wondering and interested to know about this delay time. Please bear some of your time:). Thanks in advance.

Do you intend to open source the PUT function by making a Pull Request, after we fix it? If yes, it will definitely go up in my priority queue.

I have added the necessary code for rest_put () similar to rest_post() in rest_methods.c, rest_methods.h and rest_client.c If I just call, rest_put from config file, without async it works fine. I could see rest_put() is called and do the necessary steps. And am trying to call async from config file as, async(rest_put("http://***url*** <http://***url***%20> ", "$fU,$tU,$ci ", "application/json", "$var(body)", "$var(ct)", "$var(rcode)"),resume_put); Further debugging I got some info that I can share with you so that you can help me out easily. Instead of calling rest_put asynchronously I have tried to call rest_post async . I could able to see that HTTP request went out(from Wireshark traces) and I got 4xx response for the same. With my code changes in place and when I call rest_put, am not seeing HTTP request sent out. Assuming rest_put only is not working, there should be some libcurl stuffs not handled properly in 'start_async_http_req' for 'REST_CLIENT_PUT' case. Am attaching the files that contains code changes for rest_put only. I have removed other code in order to reduce the file size. Can you please take a look guide me here?. Please let me know if you need more information on this.

If you need that, you will have to use 2.1+ Async rest_put() is currently not implemented, but its logic would be fairly similar to the GET and POST counterparts.

Is it possible to change in asynchronous mode in 1.11 version? If not, is there a way to achieve asynchronous REST calls for the version of opensips what we are using? Also I see from documentation, The following functions may also be called asynchronously: * avp_db_query<http://www.opensips.org/html/docs/modules/2.1.x/avpops.html#id294986> * rest_get<http://www.opensips.org/html/docs/modules/2.1.x/rest_client.html#id293741> * rest_post<http://www.opensips.org/html/docs/modules/2.1.x/rest_client.html#id293886> * exec<http://www.opensips.org/html/docs/modules/2.1.x/exec#id294052> Can rest_put can also be called asynchronously if we use 2.1 version ?
