VoIP / SIP / Telephony / Carrier
Carrier-grade voice infrastructure with global termination and redundancy.
AiCX's VoIP, SIP, Telephony, and Carrier practice provides carrier-grade voice infrastructure: SIP trunking, redundancy, global termination, and the underlying voice plumbing that powers contact centers, custom telephony, and CPaaS applications at scale.
We operate as a CPaaS-class voice provider with direct Tier-1 carrier interconnects, geographic and route diversity, sub-50ms latency targets, and the operational discipline that production voice demands. Whether you need SIP trunks for your CCaaS, voice termination for a custom application, or a full multi-region voice architecture, we deliver carrier-grade infrastructure with managed-service operations.
Most clients use us as their voice carrier alongside other CCaaS or application infrastructure. Some use us as their full voice partner — number management, termination, origination, branded calling, and reputation management as one integrated service.
The difference is in how we run the program — not the deck.
Plenty of vendors can quote you a seat. Few can deliver an outcome. Here's what changes when AiCX runs your voip / sip / telephony / carrier program.
