No Call Pop Up To System User

As we had assigned the exophones to the system user whenever a customer calls no system user gets a notification nor does any pop-up comes in the system. Moreover, Noone can justify which kind of call “Ringing”, “In Progress”, “No Answer”, “Completed”, “Busy” and “Failed”.

Unable to Fetch any outgoing call record in ERPNext system which are done by the System user by their exophone mobile as only able to see the call records of incoming calls only. However, No call Duration is shown for how much time period/span the communication has taken place between customer and system user. Unable to fetch the recording URL from exotel.

Thanks In Advance
