User's Manual 32. CRP Overview
32 CRP Overview
The device's Cloud Resilience Package (CRP) application enhances cloud-based or
hosted communications environments by ensuring survivability, high voice quality and
security at enterprise branch offices and cloud service customer premises. CRP is
designed to be deployed at customer sites and branches of:

Cloud-based and hosted communications

Cloud-based or hosted contact-center services

Distributed PBX or unified communications deployments
The CRP application is based on the functionality of the SBC application, providing branch
offices with call routing and survivability support similar to the SAS application. CRP is
implemented in a network topology where the device is located at the branch office, routing
calls between the branch users, and/or between the branch users and other users located
elsewhere (at headquarters or other branch offices), through a hosted server (IP PBX)
located at the Enterprise headquarters. The device maintains call continuity even if a failure
occurs in communication with the hosted IP PBX. It does this by using its Call Survivability
feature, enabling the branch users to call one another or make external calls through the
device's PSTN gateway interface (if configured).
For cloud providers, CRP ensures uninterrupted communications in the event of lost
connection with the cloud providers’ control systems. For distributed enterprises and
contact centers, CRP is an essential solution for enterprises deploying geographically
distributed communications solutions or distributed call centers with many branch offices.
CRP ensures the delivery of internal and external calls even when the connection with the
centralized control servers is lost.

One of the main advantages of CRP is that it enables quick-and-easy configuration. This is
accomplished by its pre-configured routing entities, whereby only minimal configuration is
required such as for IP addresses to get the device up and running and deployed in the
network.
