I have a Partner ACS with a large pc type VM. Has been working fine for months. Today they called and said when customers call in they get the AA and when they transfer out of the AA to an ext the display on that ext says transfered from ext 18. Ext 18 is a valid ext with a mailbox. If you dial 18 from the AA you are transfered to the operator. I'm not overly familiar with the Partners but I have installed a few. Thank you.
