What Callcentric Wholesale does

Callcentric Wholesale is a private wholesale telecommunications company headquartered in New York that provides international VoIP origination and termination services between IP networks and the PSTN. Its customers are primarily telecommunication carriers that resell high-quality, low-cost minutes to their own residential and business subscribers, along with calling centers, call shops, and calling card businesses. The company has deliberately focused on traffic lanes between developed and developing countries, avoiding overbuilt East-West routes and capturing growing prepaid calling card flows into emerging markets.

The core technical platform is a globally interconnected VoIP network supporting SIP, H.323, and TDM interconnect (T1/E1/DS3 with PRI or SS7), anchored by the proprietary Route Quality Indicator (RQI) engine that re-evaluates every route every five minutes based on latency, packet loss, post-dial delay, answer-seizure ratio, average call duration, and false-answer supervision metrics. Supporting systems, including billing, monitoring, provisioning, routing, and a per-line monitoring tool that auto-disables faulty PSTN channels and alerts the NOC, are designed and developed in-house. Multiple Tier 1 ISP backbones, redundant optical carriers, and redundant switches provide carrier-grade redundancy.

Callcentric monetizes through usage-based per-minute origination and termination fees paid by carriers and termination partners on Net-15 terms in USD, complemented by retail VoIP subscriptions and pay-as-you-go service through the Callcentric.com sub-brand. GTM is sales-led and application-gated, requiring prospective partners to meet minimum channel, equipment, and bandwidth requirements before sales engagement. Operations are supported by a web-based reporting system providing real-time traffic graphs, CDR export, quality metrics, and integrated help desk routing to the NOC.
