In the example on the left, when the calls coming from 555-1237 or 555-1238 are not answered, if you subscribe to the Centrex service provided by your local telephone company, these calls will be switched to the console telephone (EXT 11 in the example).

1.An external call comes in on line 4 (telephone number 555-1237 or 555-1238) on the original system telephone (EXT 12 or EXT 13).

2.If the call is not answered during the CSL delay time set on the original extension, (20 seconds for EXT 12 or 16 seconds for EXT 13), the console telephone (EXT 11) will ring and display

EXT XX RING.

3.Press the [LINE 4] key if line 4 is idle on the console telephone (EXT 11). Dial the Centrex access code (provided by your telephone company) then the ringing line’s seven- or ten- digit phone number, (as directed by your phone company).

NOTES:

•If no one answers the call at the console telephone for 10 seconds, the originating extension will ring again.

•Outside calls will be answered by the auto attendant (see the 1080 user’s manual for details).
