Centrex operation
Centrex service call example
In the example on the le, when the calls coming
from 555-1237 or 555-1238 are not answered, and
if you subscribe to the Centrex service provided
by your local telephone company, these calls are
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) rings and displays EXT
XX RING (XX is the desired phone extension
number).
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 ring again.
Outside calls are answered by the auto
attendant (See the 1080 user’s manual for
details).
