Hi, Could you send along the log file? To generate the log file, you just need to specify log filename in logging config for the pjsua_init(), e.g: log_cfg.log_filename = pj_str("c:\\data\\pjsua.log"); Please also make sure APS server is installed in the device, please see https://trac.pjsip.org/repos/wiki/APS.
