Setting up phone integration

Hello Creatio Community,

I started using a trial version of Marketing Creatio version 8.08.4807. I was trying to set up phone integration , using Webitel as phone integration connector. I downloaded webitel call manager using the link :  https://marketplace.creatio.com/marketplace/9892/install  and then installed it using Application Hub.

Also I followed the steps from link : https://academy.creatio.com/docs/user/more_apps/phone_integration_connectors/webitel/set_up_integration_with_webitel ,

When I try to call a contact , it does not show any event in call tab.

Can someone help me ?

Thanks
