Sorry, my log were filtered, I have ERRORS because of pkg_mem. This will help for code digging for silent reply. build_res_buf_from_sip_req: out of memory print_uac_req: no pkg_mem t_forward_nonack: failure to add branches Aurelien Aurelien Grimaud a écrit :Hi, I have a route block which issues a t_relay(). route[1] { t_relay() ; } If this t_relay fails, is there a default reply from openser to caller ? Let me explain. In my logs, I have an incoming INVITE, followed 2 ms after t_relay by an ACK from uac. The callee never gets the INVITE. UAC -- INVITE --> openser : t_relay() UAC -- ACK --> openser I guess UAC gets a default reply from openser, I want to make sure of it. I have no ERROR in my log file. UAC logs tells that openser hang up with a server internal error (no sip trace, no sip code, just an indication of what cause could be). This is openser 1.2.0 Is anyone aware f this issue ? Could someone point me where the 5xx reply is in source code ? If it is a default reply, is there now an ERROR message before reply ?
