the part nobody prices in
You are the only buyer on this site who can check whether your vendor is telling the truth about numbers.
Every support vendor selling to a global brand says some version of "we can give you a local number in your markets." Most buyers have no way to test that sentence. You do. You know that provisioning in most jurisdictions requires a local legal entity, proof of a local address, and either a telecom licence or a carrier relationship in that country — because getting those is what your own regulatory team does for a living.
So ask the question you would ask a wholesale partner. Not "do you support Germany" — "who holds the number, and what happens to it if we leave." A vendor reselling a single upstream supplier answers the first and goes quiet on the second. We will not tell you we already hold numbers everywhere.
The second thing that makes telecom different is the shape of the volume. Most industries have peaks you can forecast — a season, a promotion, a launch. Yours has a fibre cut. Four hundred people ask the same question inside an hour, none of them need a person for it, and every one calls back in twenty minutes if the first answer carried no restoration window.
That combination — one correct answer, enormous volume, an hour nobody staffed for — is the clearest case for automation on this site. It is also why the human half matters more here.
