Hi,
I am using 3cx version 18 (update 16)
I could initially add 001 extension. Recently, i deleted this extension and tried to create 001 again. However, i could not and the error is
"Cannot use this number try another one". Pls see below
I tired other 3 digit extension starting with 0 , also cannot add.
However, i can add 3 digit extension starting with 1 e.g. 103
Can anyone advise how i can fix this issue ? (adding 3 digit extension starting with 0)

Thanks.
Regards,
Kwang Mien
