Evolve Calling Card¶
Evolve ® Calling Card (CC) service offers an easy and flexible way to organize a complete set of calling card offerings. With CC, Service Providers are able to create different rates, rate plans, offerings and can add large numbers of pre- or post-paid calling cards quickly and easily.
Service Providers can create detailed and customizable product offerings and edit additional features such as announced and unannounced rate parameters, speed dial lists, and minimum and maximum times per call.
Real-Time Rating Engine¶
The Real-Time Rating Engine is the foundation of CC, giving Service Providers the charge and policy control needed to translate monetized services into product offerings.
The Real-Time Rating Engine allows Service Providers to build flexible rates based on factors such as time of day, day of the week, and country of call origin.
Additionally, the Real-Time Rating Engine allows Service Providers to tailor usage policy and billing sequence rates. For example, allowing a rate of 3 cents per minute for the first 5 minutes and 6 cents per minute after 5 minutes is a simple rate that can be added through the CC web-based user interface.
Customizable Prompts¶
CC not only includes the Real-Time Rating Engine as a feature, but also provides a large amount of customization in regard to available prompts and languages used for announcements.
Separation of Roles¶
CC is designed for multi-tenancy with three distinct roles. These roles are Platform Owners and Service Providers. Each of these roles have their own responsibilities and functions.
Platform Owners
The Platform Owner is the entity that deploys the network which runs CC. The Platform Owner is responsible for defining physical egress routes and other network specifics. Additionally, Platform Owners create and define Service Providers.
Service Providers
A Service Provider is the entity that offers CC as a service. The Service Provider is responsible for defining the call rates, allocating lots, and defining product offerings.
Signaling¶
CC is deployed in the network and is designed to handle SIP signals to process call rating treatment prior to the call being established.
The rest of the chapter details the specific call flow of various call treatments.
