To complete my understanding of connecting through SIP, help me tear this apart.
register => 102:email@example.com
The place, fromdomain.com, needs to be the domain/ip address of the computer hosting the X-Lite softphone, right?
For example, I have a domain set up to redirect all 5060 traffic to my PBX. When I am on the network, my softphone works great. It connects and can make outgoing and receive calls. However, when I am on another network, the softphone fails to work. This is without updating the register line.
In order for this to work, does * need to be aware of the IP/domain that my softphone is on?
