No sound in Asterisk, running on personal network

I have downloaded Asterisk, uploaded and downloaded all modules. I added two extensions, and that was all i did for configuration. No need to port forward, since I am on an internal network. I have X-Lite, and can get it to register, and when I call *65, i see in Asterisk CLI that it is relaying the extension, but I hear nothing.


Perhaps, you will need to post your configurations here. Otherwise, readers have no idea how to help.
