Hi all, I am testing with pjsip + CsipSImple with an asterisk pbx. During the tests I found a problem that appears when I call from a terminal A yo terminal B, but I end the call from terminal B (call receiver) Under such conditions terminal B hangout but terminal A are still assuming that call continues. The log I extracted from terminal A is the following. Any Idea how to fix it?
