Hi

Thanks for the attachments it helps to see the full problem.

You seem to have multiple problems and we need to resolve each one step by step.

If you would like to PM me I can give you some information to allow us to remote into your system and help you with it.

If possible we would like to include your current 3cx partner so we can assist each other.

We have not worked with TMG server with a 3cx installation (have worked each individually) and so our support would be free of charge as we view it as a learning experience, with the caveat that we make no guarantees that we can fix it.

Send me a pm if you want to proceed as I feel it will be a lot to try to explain in a forum post.
