Hello,
I am not interesting to solve just my own problem, I believe this issue is existing on curl library that effects Kamailio side. My study just use CURL lib to use HTTP Post function, it is straightforward task.
I wonder, it there anybody who gets same issue ? Curl [bug](https://github.com/curl/curl/commit/1835cb916e0d40eb8bc1165d5627a0b64f911bac...) is could effect Kamailio side which is similar to Kamailio [issue](https://github.com/kamailio/kamailio/issues/2466)
Regards, Melek
