Every call delivered with its original caller ID
Premium CLI is the default route class across most of our A-Z footprint. Your customer's number appears on the destination handset — no refile, no substitution.
CLI preserved end-to-end
P-Asserted-Identity and From-header pass through untouched to the terminating operator.
No CLI refile
We reject downstream carriers that substitute or randomize the A-number. Enforced continuously.
Transparent monitoring
Per-destination ASR, ACD and CLI-delivery percentage exposed in your portal.
Quality SLA
Target ASR > 55%, ACD > 4 min on all Premium CLI destinations.
STIR/SHAKEN ready
Attestation A on US/Canada Premium routes for legitimate calling identity.
Contract-grade
Written commitment on route class per destination. No silent downgrades.

How CLI delivery is enforced
A four-stage pipeline. Every stage is instrumented, and any deviation removes the route from rotation within minutes — not the next quarterly review.
- 01
Inbound INVITE
Your PBX sends the INVITE with the original A-number in P-Asserted-Identity and the From-header.
- 02
Route class match
Our routing engine selects a direct Premium CLI trunk based on B-number prefix and current quality scores.
- 03
Direct handoff
The call is handed to a Tier-1 partner bound by a contractual no-refile clause with financial penalties.
- 04
Delivery audit
Automated test calls sample CLI delivery per destination every hour. Deviations trigger route removal and NOC alert.
A missing A-number is a lost customer.
When a caller ID is dropped, spoofed, or replaced with a random national number, three things happen at once. The recipient doesn't recognize the caller and rejects the call. Return calls land on a dead number. And your outbound campaign quietly loses 40-70% of its answer rate.
Premium CLI exists because the wholesale voice market silently normalized this loss. We refuse to.
Regulatory compliance
Premium CLI is not just a quality label — it is how you stay on the right side of the caller-ID rules that regulators are now actively enforcing.
STIR/SHAKEN (US/CA)
