I’m just getting started with VitalPBX, but I’m having trouble registering a trunk. Could you please help me identify what I might be missing or doing wrong? I’ve been following the Udemy VitalPBX lessons step by step, and I did everything exactly as shown in the video. I’ve also included my system information and a screenshot of the trunk registration. Thank you in advance!

You don’t need a `Local Secret` if the authentication is outbound.

Some other recommendations:

- Empty the Contacts field. This is created automatically; it is only needed when you have multiple IP addresses or domains for outbound calls.
- Select the option `IP` in the field `Identify By.`
- Select the `Default PJSIP Profile` in the field `Profile`.
- Set a valid `Trunk CID.` Most providers required a valid outbound CID to place calls.
- Set the parameter `Overwrite CID` to `If not provided.`

It is registered now. Thank you!  
But the problem is when I try to check and call this number. It says it’s not registered(In our language.) Do you have any idea about it? I did inbound route too.
