I'm a newbie to VoIP and only have limited knowledge of unix. So I've been following this article to set up a test workaround for company's telephony application. I installed Ubuntu on Mac OS X with Virtual Box, somehow just got stuck at step 5. I got error 408 when trying to register extension in X-Lite, the soft phone I used. I searched about similar issues and seems error 408 is related to a domain problem. The author only mentioned "login to your FreeSWITCH install by extension and IP address". I guess my question is which IP address should I use as the domain? The IP address of the guest OS and or the host OS? I tried both and neither of them worked though. Any insight is appreciated. Thanks!
StackOverflow is a site for software programming questions, and your question belongs rather to Serverfault.com.
In regards to IP addresses, your FreeSWITCH server should be reachable for the SIP client. So, you need to organize your network settings in a way that external hosts in the LAN can connect to the FreeSWITCH. I don't know if it's supported in MacOS, but VirtualBox should be configured in bridge mode, so that the guest OS gets an IP address from the physical LAN.
