    Ok, I am new at this.

    The first time I loaded it, everything was fine.

    However after a restart, it says it cannot resolve external IP hence it can't register lines.

    I got around it by plugging in a no-ip.com adress manually for now, but any ideas why this is happening.

    try using a stun server in the voip properties, dont forget to open port 3478 for stun traffic.
