Badges for Callin.io

Free for Callin.io to embed. Each badge links back to this profile and is served from aireceptionistsranked.com. Rank badges state a position in our published-data order (price published first, then how complete the public facts are), not a score or a test result. If the position changes, the old badge URL redirects to the current one, or to the Listed-on badge if Callin.io leaves that list. Dark versions: replace _light_ with _dark_.
