Hello everyone. I successfully installed the current version of elastix, everything went smoothly. I used the web interface to setup a couple of extensions for testing and I configured the softphone (X-Lite 4). So far, I'm able to dial the extensions and receive the calls, but there's no sound. Actually, there is, but it's more like random noise. I'm working in LAN. Could it be a codec issue? where should I begin the troubleshooting? Thank you.
