Call Routing
Policy-driven call routing across queues, skills, time-of-day, and platform boundaries.
Call routing is where business rules meet the phone network. We implement routing policies across PBX, softswitch, and contact-center layers—skills, schedules, overflow, and geographic or customer-based rules—so calls land with the right team without tribal knowledge locked in one admin’s head.

- • Changes require risky live edits
Expected outcomes
- • Documented routing matrix and ownership model
- • Implemented policies with staging validation
- • Safe change procedures for operators

FAQ
Related but not identical. Call routing often means agent/queue policy; voice routing / LCR focuses on carrier and cost/quality path selection. We frequently do both together.
