[OpenSIPS-Users] How to answer a call with a wav file?

[Eran Leshem]

Hi,

I tried adding the line that you suggested, but I still get an error
message.
The route that I wrote is:

```
route[play_audio] {
  rtpengine_offer("to-tag=$ft from-tag=$ft");
  append_to_reply("Content-Type: application/sdp\r\n");
  $var(body) = $(rb{re.subst,/(IP4.).*/\1$si/g});
  t_reply_with_body(183, "Session Progress", $var(body));
  rtpengine_manage();

  $var(play_duration) = 300;
  rtpengine_play_media("file=/path/to/music.wav to-tag=$ft", $var(
play_duration));
}
```

The error message that I'm getting is:

ERROR:rtpengine:rtpe_function_call: proxy replied with error: No
participant party specified
ERROR:rtpengine:rtpengine:rtpengine_playmedia_f: could not start media!

Any idea on what is wrong?
