> ASTERISK-27169 introduced OAuth support into res_xmpp. The change was cherry-picked into Asterisk 13 as commit 54e3ac402ff167ba2463b386ea25fa5327be86c6. Unfortunately, it seems like the cherry-picked code does not actually work , likely due to func_curl changes in Asterisk 14 and higher (probably commit 6bbcfb34bd411ec88a02e6c655b0d5b9821495a4). The token is correctly refreshed via func_curl, but the resulting XML is never copied to the read buffer. The error message displayed claims that "CURL is unavailable.", which is inaccurate -- CURL is available, only the XML is never passed back. The relevant log lines are shown below. I am currently trying to work up a patch to fix this in Asterisk 13.
