I have installed Asterisk, and i have already configured sip.conf and extensions.conf, but when when i try to connect two X-Lite softphones appears the next error:

Call Failed: 408 Timeout

I dont get anything in asterisk Console

Are asterisk and x-lite(s) on the same network?

Yes, both are on the same networks, but i have installed Asterisk on VMWARE running on a 2003 servers.

I’m doing this as well. I had to make sure that my NAT settings were correct.
