Featured Reviews

Abeer ELADAWY - PeerSpot reviewer
Deputy Senior Manager, Customer Interaction Management at DEWA
Provides omnichannel AI features and has good routing capabilities
The routing capabilities are excellent. We have priority routing set up for VIP customers, disabled customers, and those with special needs, ensuring they receive prompt and efficient service. We have implemented a use case where AI helps when a customer calls and says, "My bill is high." The AI searches the customer's profile to check if the high consumption is real or just a misunderstanding. If it is high, the AI creates a notification for the backend to check the issue. The system automatically generates the bill and the notification for the agent, who then views and either submits or rejects the notification. I recommend using the solution for all the features I have mentioned before, including the excellent AI experience, omnichannel, self-service, and customer journey features. I rate it a nine.

Freelancer at a consultancy with 51-200 employees
Has efficient automation features and the ability to integrate with multiple systems
The initial setup is quite difficult for the latest versions from 2020 and beyond and can take about four to five hours. It can now be deployed on the cloud. Oracle offers the same images for on-premise and cloud deployments, making it easy to switch between the two. I created the docker image using VM and completed the setup in a few hours.
