    Hi,

    I like use 2 digit extension numbers on my system. It's practical for me.
    But the system doesn't allow some numbers:

    77, 81

    When I try use this numbers the system show "Given DN number cannot be used".

    Possible modify the DN numbers? And if yes how to? I was search but don't found.

    Thank you

    Tony

    Officially not. Some of hem can be changed in 'System extensions' in the Dashboard or in corresponding menu (like Digital Receptionist,, Queues, Ring Groups). To change No. 77 probably the only way is to edit the backup file -- change it to something else free like 07 or other number, and then restore the backup. Be careful, as this may result into non-working configuration. Make another backup before and save into another location to restore the PBX or reinstall it, if crashed.
