How it works
From your network to
your customers' call experience
Call Flow sits within your existing infrastructure. You retain full control over the network — your customers gain the flexibility to manage their own IVR journeys.
01
You deploy Call Flow
Call Flow is integrated into your network using whichever of the three integration paths suits your infrastructure — Web Routing, SIP Gateway, or REST API. No disruption to your existing services.
02
Customers build their flows
Each customer gets access to the visual Call Flow designer. They build menus, routing rules, and call journeys themselves — without raising a support ticket or needing any programming knowledge.
03
Calls route seamlessly
Published IVR flows are assigned unique run keys and become available as destinations within your routing platform. Your customers' callers reach a professional, self-managed IVR — powered by your network.
Integration options
Three paths. One platform.
Your choice.
Call Flow is designed to work alongside whatever telephony infrastructure you already operate — not replace it.
Option 01
Web Routing
For carriers who manage number ranges and routing schedules for their customers. New Call Flow diagrams automatically appear as destinations within your Web Routing scheduling platform.
Ideal for
Service providers managing number ranges on behalf of customers who want IVR as part of a bundled telephony offering.
Option 02
SIP Gateway
No number routing platform? No problem. IVR scripts are assigned unique run keys which are mapped to outbound destinations through your SIP Gateway's outbound routing rules.
Ideal for
Operators who don't provide a customer-facing routing platform but want to offer IVR as a standalone managed service.
Option 03
REST API
Already running your own routing or management platform? Use our fully documented RESTful API to retrieve active Call Flow diagrams and their run keys for use within your own systems.
Ideal for
Operators with bespoke routing platforms who want to integrate Call Flow data natively into their own tools.
