c) Resolution:

If the issue is immediate call drop after dial, then mostly issue is due to Avaya.

How to activate default IVR Call flow via EPM/AEP

  1. Login to EPM / Avaya Experience portal/ AEP

2. Under system configuration, select Application

Select the Application Eg:- CBGApplication

Here, either we can keep in Single-mode or load balancer.

Currently, the application is in load balancing mode as there are 2 URLs configured.

Select the application and edit the URL to the dummy URL

Eg: https://10.5.23**.12345:8443/Interaction/Start

Once the URL is changed, Click on verify and ensure the application is not reachable and then save the changes.

Issue Resolution 2:
