Flow patterns (42-month cumulative)

Inbound (numbers acquired)

Direct transfer from another RespOrg	210.0
Harvested from disconnect pool	3.0
First assigned from spare pool	132.0
Reactivated own disconnects	0.0

Outbound (numbers lost)

Direct transfer to another RespOrg	330.0
Standard disconnect aging process (3+ months in DISC)	0
Abbreviated disconnect period (1–2 months in DISC)	86
Released directly to spare pool	105.0

Of the 86 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

Probably best described as a Telecom Broker, offering a range of voice and internet services, including traditional phone service, VOIP, Tollfree, voicemail, various levels of business internet and managed IT services. They could be considered a Small Phone company or VOIP service but I'm guessing they are more of a broker, selling other services than providing the majroty of these things themselves.
