operator absent error when operator line "0" is forwarded

[infosyst]

Normally people on site can press "0" to reach the operator however after hours the operator line is forwarded to another department at extension 1234.
If we try and dial "0" then we get the message "operator absent" alternatively we can dial "1000" and that will get us to the operator or where the operator is
forwarding to.

What can I do to get "0" to work even if the operator is being forwarded?
Mitel 3300.

What do you mean by "the operator"? Do you have an IP console?

Another thing... what is 0 configured as on the phone system?
Maybe this helps:

 Our operator uses a 5540 IP console.

Thanks, read the post and was able to fix the issue by setting up a speed dial.
