  1. Hi Dear,
    Thanks for the useful informations you are sharing on this website,
    I want just to add to this topic, of direct IP calls, that you can make Direct IP calls just by enabling your account and disabling the random ports option, and there is no need to register an account, also you can add that to make a call to the receiving endpoint’s second account (second Line) you need to specify the following transport port 5062.

    Kind regards,
