Real-time CDRs
Second-by-second call detail records via API, SFTP, or dashboard export.
Fraud shielding
Real-time IRSF and PBX-hacking detection with auto-block thresholds you control.
Dynamic LCR engine
Least-cost routing re-ranks every supplier every 5 minutes on live ASR and PDD.
Flexible billing terms
Prepaid, postpaid, or credit-line billing with daily invoicing available.
Coverage

The call flow
A-Z call termination routing. Sub-second route selection.
Every call your switch sends runs through a six-step process designed for full QoS visibility.
Step 1
01IP Authentication
SIP arrives on your authorized IP, checked against your ACL.
Step 2
02Codec Negotiation
G.711, G.729, Opus and AMR-WB, transcoded at the SBC.
Step 3
03LCR Scoring
Live cost, ASR, PDD and jitter scored for every route.
Step 4
04Route Selection
Best route chosen by tier, with a backup already prepared.
Step 5
05Quality Monitoring
ASR, PDD and MOS logged live. Anomalies alert the NOC.
Step 6
06Answer or Release
Live CDR with route and attestation. Auto-failover in one ring.

FAQ
Wholesale voice termination, answered.
Wholesale voice termination is the bulk routing of outbound calls between carriers for final delivery on the destination network. Acepeak accepts your SIP traffic, runs every call through real-time least-cost routing against direct Tier-1 interconnects, and returns full CDR, ASR, PDD, and MOS data to your portal in real time.
CLI routes deliver a verified Caller ID number end-to-end with STIR/SHAKEN attestation — required for enterprise and US compliance. Non-CLI routes are cost-optimized for high-volume A-Z traffic where caller ID verification is not a primary concern (calling cards, survey traffic, internal corridors). We price and label both separately and never blend them without consent.
Most accounts are provisioned and test-calling within 24 hours. Commercial traffic flows once IP Access Control, credentials, and codec preferences are confirmed — typically same-day for Basic and Platinum tiers. Custom CLI corridors require 3–5 business days for hand-tuning and per-country compliance review.
Yes. We auto-provision SIP trunks for Asterisk, FreeSWITCH, 3CX, Cisco, Yealink, Polycom, and most carrier-grade softswitches — matching your codec, signaling, and encryption preferences without any platform migration.
Machine-learning fraud detection scores every call in real time. High-risk destinations auto-rate-limit, IRSF (International Revenue Share Fraud) detection catches anomalies within seconds, and the 24/7 NOC reviews escalations and contacts you immediately. All included — no fraud-protection upsell.
Basic CC: 99.9% uptime with 30-min P1 response. Platinum Tier-1: 99.99% uptime with 15-min P1 response and a named account manager. Custom CLI: custom uptime targets with 10-min P1 response, dedicated account manager, and NOC engineer access. Service credits apply automatically against the next invoice if SLAs are missed.
