    Somebody from this address: 20.1.1.1 was trying to register on PBX. Most probably an attack. Normal to have such messages from time to time. Be sure all passwords you use, are strong enough.

    Normally you should install the PBX on local address like 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16, as defined by RFC 1918.
    The address 20.1.1.1 is a public IP address and if you use it as private one, the PBX would not function properly. The case above means the address will be blocked for 1800 sec (default security setting), as the PBX received registration attempt from itself. By default extensions are not allowed to register from public networks. You may have other configuration issues too for causing the above event.

    Please review your settings and if necessary reinstall the PBX (you can't change local address of the PBX without reinstalling).
