Trying to get all the extension

Need help in getting all Extensions and Call log records.

I am logged in as 'Data Analytics' users.

There is a 'Corporate Directory' app created by a different group

1. App is private
2. Application scope is set Read Accounts, Read Call Logs

Analytics group created another app 'Analytics Test App'

Primary purpose is to invoke REST APIs and get account information and call records.

{{RC_SERVER_HOSTNAME}}restapi/v1.0/account/~/extension/

This call does returns about 6 entries with two as unassigned.

{{RC_SERVER_HOSTNAME}}restapi/v1.0/account/~/extension/~/call-log

Return 2 entiries. Some test data I created personally.

I need to entire company directory and all call records. What settings should I use to enable this functionality.

BTW .. I also created a support ticket.

Thank you
