Hi,<br>
<br>
Note:<br>
The methods of rtpproxy-module will only replace the IP, if the<br>
Kamailio can access the RTPProxy.<br>
<br>
How is your RTPProxy connected to your Kamailio? Socket or TCP? Do you<br>
have the Kamailio FIFO enabeld?<br>
If you have the fifo enabled, you should check the following:<br>
<br>
kamctl fifo nh_show_rtpp<br>
<br>
You should see, that the Kamailio is connected to the RTPProxy. If no,<br>
then that is your problem.<br>
If the RTPProxy is connected and is listening on the TCP socket, then<br>
you can do an ngrep to see the communication between Kamailio and<br>
RTPProxy, which might help you further with your investigation.<br>
