After following the Install Instructions you will have a Clearwater deployment which is capable of handling on-net calls and has a number of MMTel services available through the built-in TAS.
Clearwater supports many optional extra features that you may chose to add to your deployment. Descriptions of each feature along with the process to enable it on your system can be found here.

Clearwater has a number of call features provided by its built-in TAS, including:
Clearwater’s support for all IR.92 Supplementary Services is discussed in this document.
Scaling and Redundancy¶
Clearwater is designed from the ground up to scale horizontally across multiple instances to allow it to handle large subscriber counts and to support a high level of redundancy.
