Auto Attendant has five possible settings: 1) STAC does not answer incoming calls. 2) STAC answers incoming calls after two rings and puts calls On Hold. 3) STAC answers incoming calls after six rings and puts calls On Hold. 4) STAC answers calls after two rings and plays a short outgoing message to the caller before putting the line On Hold. - Page 24 For example, if AA is selected on one control surface, it is active on all. When this button is inactive, STAC will not automatically answer incoming calls. When the button is active, incoming calls will be automatically answered.

- Page 34 We can, however, make the following general suggestions: 1) If you cannot remotely access STAC IP , don’t assume that it’s always the fault of the network on the STAC side. Double check the STAC IP settings (especially the netmask and gateway settings).

- Page 44 INUS EATURE setting DIP Switch 8 on the STAC mainframe to ON, you can apply a full program feed to the STAC, including caller audio. The STAC will attempt to dynamically remove each caller from his outgoing feed. This adaptation re- quires a completely unprocessed and linear signal at the Send Input, like that coming directly off the console.
