Jose, instead of pjsua_conf_connect(), I used pjmedia_conf_connect(pjsua_var.mconf, 0, recorder_port, 0) and pjmedia_conf_connect(pjsua_var.mconf, call_info.conf_slot, recorder_port, 0) to connect the soundcard and caller to the recorder. This works for me. I record the caller and called parties' voices. Your code looks fine. I suspect there is something else connected to the conference bridge which is producing those loud static noise. Since you're hearing the wav file being played, your connection is picking up the intended and as well the unintended sources. I presume you are playing the wav file at the calling device ? ________________________________ From: Jose Suarez <jsuarez@xxxxxxxxxxxxxx> To: pjsip list <pjsip at lists.pjsip.org> Sent: Sun, December 6, 2009 1:47:42 AM Subject: Call Recording - Simple question Hi all, I want to record a call. I'm developing an automatic dialer. I make a call and then play a wav file. During that call I want to record it. For do that I do the following function: CDialerSIP::e_i_SIP_RetRecord CDialerSIP::record () { pj_status_t pjStatus; std::string strLog; std::stringstream ssLog; pjStatus = pjsua_recorder_create (&(pj_str("./record.wav")),0,NULL,0,0,&m_pjRecorderId); if (pjStatus != PJ_SUCCESS) { m_oLogger.write ("record - pjsua_record_create - Fall?.", CDialerLogger::iLogError); return CDialerSIP::i_Record_Error; } pjStatus = pjsua_conf_connect ( pjsua_call_get_conf_port(m_pjCallId), pjsua_recorder_get_conf_port(m_pjRecorderId)); if (pjStatus != PJ_SUCCESS) { m_oLogger.write ("record - pjsua_conf_connect - Fall?.", CDialerLogger::iLogError); return CDialerSIP::i_Record_Error; } sleep (10); pjsua_conf_disconnect (pjsua_call_get_conf_port(m_pjCallId), pjsua_player_get_conf_port(m_pjRecorderId)); pjStatus = pjsua_recorder_destroy (m_pjRecorderId); if (pjStatus != PJ_SUCCESS) { m_oLogger.write ("record - pjsua_recorder_destroy - Fall?.", CDialerLogger::iLogError); return CDialerSIP::i_Record_Error; } ssLog << "record - Ok"; strLog = ssLog.str(); m_oLogger.write (strLog, CDialerLogger::iLogInformation); return CDialerSIP::i_Record_Normal; } m_pjCallId and m_pjRecorderId are members of the CDialerSIP' class. I recorder during 10 senconds, in that time I'm playing a wav file, so the recorder file should contain samples of that file, but the recorder file only has silence with very loud noise, in that noise you can hear very very loud the samples of the playing file. Do you know what happen? Thanks in advance Jose -------------- next part -------------- An HTML attachment was scrubbed...
