Outbound that survives compliance review. And the carrier filters.
SIP trunk for exchanges, custodians, and crypto platforms running KYC, withdrawal verification, retention, and onboarding outbound. Dedicated CLI under our license, STIR/SHAKEN in US/CA, encrypted transport end-to-end.

Why crypto outbound stops working at scale.
Carriers downstream filter crypto-related outbound aggressively. Generic CPaaS pools amplify the problem — you inherit every other customer's flagging.
Crypto outbound is filtered hard
Carriers downstream pattern-match crypto-related outbound aggressively. Generic CPaaS pools shared across customers get caught in the same net — your KYC follow-ups stop reaching customers.
Withdrawal verifications go to voicemail
A foreign-area-code number ringing a customer about a withdrawal looks exactly like a scam. Native local presence under a real license is the only thing that holds answer rates.
CAC math collapses on retention calls
A successful exchange has retention and onboarding agents on the phone for hours. Per-minute billing turns customer success into a cost center.
What UnlimCall actually changes.
Pool tied to your platform
Native local numbers in target markets, exclusive to your traffic. Rotated under our policy so individual CLIs do not get flagged by carrier filters.
Tier-1 paths, no grey routing
Strict acceptable-use policy on the network keeps legitimate KYC and withdrawal-verification calls routing cleanly. No shared pools with grey-area outbound.
Predictable telecom on the P&L
Onboarding, retention, and KYC ops have an unmoving line item. Heavy month does not bleed margin.
