Hi Liviu, How can I point to opensips to use "libcurl-openssl-dev" instead of "gnutls-dev" -? Would be great if you guide me here.

If we find the needle (i.e. the new fd), we can throw it into the reactor and successfully exit. Otherwise, the connect operation is still going, and we need to wait a bit more. > Why select() is not used ? We don't want to do select() in the module code. The core reactor already does that for us. The module's only job in the async pattern is to produce file descriptors and feed them to the core async engine.

We have not done any development in that direction, and I assume it won't work out of the box, as we need to instruct libcurl on where to find the CA certificate before we can expect it to establish the TLS connection. As an alternative, we could add the option of disabling host/peer verifications like here [1] [1]: https://curl.haxx.se/libcurl/c/https.html Liviu Chircu OpenSIPS Developer http://www.opensips-solutions.com On 31.10.2016 16:41, Ramachandran, Agalya (Contractor) wrote: Hi team, Have you tried with https://url with async and does that work without issue ?
