I'm a beginner, so everything needs explaining in simple terms

I have set zoiper up on laptop using virtual landline.

The error comes up at the top, although I can still call out. It is showing no caller id, instead of the landline number

Please help

You can find details regarding the SIP 403 error message here.

Additionally if the receiving side of the call cannot see your caller ID/ Number ID, you need to contact your VoIP service provider since they are the ones who manage your account. They should be able to resolve this issue.
