<div>Hi there, guys. I hope you can help me. I use kamailio to comunicate some servers (each one with its own kamailio). When an user calls another, depending on the userID that will receive the call, the server redirects the call to the corresponding kamailio server. It works properly. Now, what I would like to do is to configure it so it plays a notification saying where the call is going to be forwarded.</div>
<div><br></div><div>After reading some tutorials, I tried to get it working with rtpproxy, but after configuring it, it doesn't play the clips. I am testing it with a *.wav file. The path to the file is "/usr/local/etc/kamailio/test.wav" (it's in the kamailio directory). This is my software:</div>
