Hi, I am trying to get kamailio (or more specific rtpproxy) to play a wav file when a call is setup In kamailio.cfg I have added the command in the onreply_route rtpproxy_startrecording(); rtpproxy_stream2uas("/var/log/rtpproxy/message","-1"); I am sure the command is executed and given from kamailio to rtpproxy because in syslog I see following output (using dbug output of rtpproxy) rtpproxy[2648]: DBUG:handle_command: received command "P-1 024a73d95bbe016014de647e700 /var/log/rtpproxy/behappy session 487095817;1 024a73d95bbe015f14de647e700;1" rtpproxy[2648]: DBUG:doreply: sending reply "E6#012" rtpproxy[2648]: DBUG:handle_command: received command "R 024a73d95bbe016014de647e700 487095817 024a73d95bbe015f14de647e700" rtpproxy[2648]: DBUG:doreply: sending reply "0#012" The "R" command is the startrecording command and that is indeed working perfect. (recording to /var/log/rtpproxy) The "P" command is the "Playing or stream2uas" command. Seems that the message rtpproxy gets differs a bit from the one I found in the rtpproxy manual from the manual : P[args] callid play_name codecs from_tag to_tag Direction of the playback is defined by the order of the from_tag and to_tag parameters. R callid from_tag to_tag I have used the command  "  makeann behappy.wav behappy" to convert a wavfile. It gave me a .0 and .a file which I have placed in the /var/log/rtpproxy directory  (makeann comes with the rtpproxy source and is rather a bit shy with information to say the least ;) ) There is not too much information or examples found about this so I was hoping maybe somebody on this list could help me in finding out why i'm not getting more information in syslog and why i'm not hearing the audiofile.
