It is not what is happening.
[[arbitrary text not matching known link type]] links are treated as
fuzzy links searching within current buffer. See 4.2 Internal Links
section of Org manual.

So, Org tries to search for tel:... targets and named elements in
current buffer, fails to do so, and reports that the link is broken to
the user.

I hope it is clear now that it is not unknown link type. There is no
such notion in Org as a link with unknown link type.
