CUCM - helpdesk privilege

[UsmanAkram1525]

Dear Experts,

I have configured the helpdesk user using RANK but I am facing one issue:

After configuring user rank, the helpdesk user is not able to assign end-user in Users Associated with Line phone line setting. 

for example, a page appears and users from the same rank also display for changing but when I select and click on ADD SELECTED so there is no effect 

I also tried with full access but still the same. 

Please find attached snapshot

Please suggest

Can you Share the screenshots of roles you assigned for the Helpdesk user and the configuration screenshots of Rank and ACG.
