The Roaming Optimisation Suite consists of two core subsystems:

• Optimal Router
• Retention Subsystem

Optimal Router ensures efficient call routing between roaming subscribers located in the same visited network, eliminating unnecessary voice loops via the home network. This reduces call costs and increases operator revenue.

The Retention Subsystem ensures inbound roamers remain registered in the visited network whenever coverage is available, maximizing inbound roaming revenues and improving customer experience.
