Cab Call Booking & Dispatching — 10+ Years On the Road

Why It Works

Cab and transport businesses lose revenue every time a call goes unanswered or a dispatch is delayed. Our team's decade of experience means we know how to keep call queues short, drivers moving, and customers coming back.

24/7/365 Live Call Handling

For over a decade, Sigma Outsourcing Solutions has run cab call booking and dispatch operations with a fully staffed onsite office, operating 24 hours a day, 365 days a year. We handle the call volume, the bookings, and the dispatch coordination — so fleet operators and transport businesses can focus on the road, not the phones. Our services include: Real-Time Dispatch Coordination, Onsite Office Operations, Best-in-Market Rates, Booking Management Systems, and Peak-Hour & Surge Handling.
