description: Read sending-number identity, quality, and tier state.

`GET /v1/phone_numbers` returns the Linq lines attached to your account and their current channel state. Sends select among eligible lines.

The `quality` field preserves the token reported by the channel. Empty means no rating has been reported. An unfamiliar non-empty token remains visible without a `quality_band`; a recognized token carries both. Treat `quality_band` as Linq’s provisional placement, not a replacement for the original token.

The messaging-tier token is also reported verbatim. This API version does not publish a numeric ceiling, so do not infer one from a token or hard-code a vendor table.
