Call Centre Infrastructure

Contact-center platform foundations: agents, queues, trunks, recording, and supervisor tooling.

We build the voice infrastructure contact centers depend on—agent registration, queues, trunking, recording, wallboards, and the integrations that keep CRM and telephony in sync. Engagements may center on VICIdial, PBX+queue models, or hybrid designs with WebRTC agent UIs.
