To send calls to a media server is not rocket science. All you have to do is rewrite the host and port of the R-URI to the IP address of the media server.
The demo-thanks.gsm file is a recording present in each Asterisk server that is installed. Let's create a number such as *100 to send a call to the Asterisk server. From now on, each number prefixed by the character, *, will be sent to the media server. In the route section of the file, insert the following just after the alias processing:
if($rU=~"^\*") {
rewritehostport("ip_address_of_the_media_server");

To do this, we will edit the sip.conf and extensions.conf files in the /etc/asterisk directory. Usually, for the purposes of testing and education, we install both Asterisk and OpenSIPS in the same server, OpenSIPS in the port 5060, and Asterisk...
