Is there a way to test the auto attendant functionality by dialing an extension number internally. Say we have all extensions within the office that have mailboxes assigned. We make a change to the DAT table Press 1 Press 2 Press 3... Now we want to test it and make sure the routing is correct without having to dial in on a CO line as this rings all the extensions first and people keep answering as the auto attendant only picks up after 4 rings. There should be a way to not only listen to the auto attendant message but actually test the keystrokes but dialing the in mail (3999) from any extension asks use to enter the mailbox number. Is there a dial code to get to the auto attendant menu?
