Internal call display with tag (Available)

Hello all,

I am using Sangoma s505 and s705 phones with FreePBX. everything works well but when I call some Extensions it shows Display name (Available) on screen thought person is on other call. it gets confuse to me when person is busy on other call and we call in it says available. I want to get rid from displaying that.
for some Extensions it just display “Display name” what I have in Extension.
I observed that when follow-me is “on” it Display Display Name (Available) on calling screen.

Is there any fix for that ? I don’t want to Display that Available tag thought Follow-me is on.

Thank you.
PB
