Alcatel Unleashed

Hi all
I faced a problem with one of the DECT phone.
The customer uses the PBX System Alcatel OmniPCX Enterprise. Configuration is performed in the system OmniVista 4760.
One phone (DECT-400) requested a password when making outbound (Public) calls.
Example: Subscriber dials 9 -->> Next, system prompts (on phone screen) for a password "Enter Password".
If you enter "0000" then the call executes successfully.
If the call is local then the system does not request the password.
I tried to change "Public Network COS" but this has no effect.
Advise please, how you can disable the password request to public calls?
Thank you for attention.

In dynamic state user (under user) disable Lock.

Dear tot3nkopf, thank you so much for your help! I managed to disable to disable the password request.
To disable the password request has been executed, the following procedure.

Thanks for the help tot3nkopf , very usefull
