    Hi ,
    Im wondering if there is way to use dynamic dns such as noip.com instead of public IP for external ext on android / iphone users ?

    Can someone please provide me with the steps

    Yes, you can. Just be sure to put the name into the 3CX PBX under Domain Name, or it will reject incoming calls

    You've probably discovered, that, for basic service, you need to forward ports 5060 and 9000 to 9049.

    Try changing the password to something really simple, just for testing, like 123. Some people have had issues cutting and pasting passwords, as blank spaces have been inadvertently copied as well.

    Have you tried registering the phone on the local LAN (wifi), or just from "outside"?

    Sorry, don't use the gateway. You will have to PM the other member if you get stuck.
    It's mentioned, however, on page 27 of the manual.
