    Many things:

    1. Run firewall checker. Application exit code should be '0'.
    2. Be sure to have correctly defined outgoing and incoming rules.
    3. Is your provider registered, what is the status of your trunk lines, etc. ?
    4. Are your extensions allowed to register outside LAN ?
    5. If using remote extensions, have you configured STUN or tunnel ?
    6. Can you make internal calls (i.e. extension to extension)

    Probably it makes sense to get acquainted with admin / user manuals before posting.
