Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 30,612.0 |
| Harvested from disconnect pool | 36.0 |
| First assigned from spare pool | 1,642.0 |
| Reactivated own disconnects | 8.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 20,096.0 |
| Standard disconnect aging process (3+ months in DISC) | 0 |

Of the 4 disconnect episodes this RespOrg has sent through aging, 100% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal, this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.
Summary
NTT Cloud is now part of AT&T so I'll group them there.
