Overview

Callr owns and operates its telecom infrastructure across multiple continents. Unlike resellers who depend on third-party networks, we control the voice path end-to-end, giving us full visibility into quality, latency, and routing decisions.

Infrastructure

2 virtual Points of Presence (POPs) in the USA and Singapore for regional call optimization. 2 physical server racks in France with dedicated fiber interconnections to major European exchanges. Redundant architecture ensures failover with no single point of failure.

Carrier Peering

Direct peering agreements with Tier 1 carriers globally. No transit providers in the voice path means fewer hops, lower latency, and better Mean Opinion Score (MOS) on calls. Our routing engine dynamically selects the best path based on real-time quality metrics.

Reliability

99.95% SLA on voice services. Redundant power, networking, and compute at every POP. Automated failover between data centers. Real-time infrastructure monitoring with proactive alerting.
