Rich Communication Services + IMS

Every layer of rich
communication. Connected.

Full-featured, cross-platform Rich Communication Services technology, from the RCS Universal Profile and IMS stack to APIs, clients and the user experience.

Complete or modular

Deploy the whole platform.Or only what you need.

Summit’s decoupled building blocks integrate with existing carrier cores, application servers and OEM clients. Operators can launch a complete experience or add individual capabilities without replacing what already works.
