previously held call.
Operating Procedure
To hold a call in progress
1. Press the switch hook; receive special dial tone.
2. Dial CALL HOLD code; receive normal dial tone.
3. The call in progress is held; the user may initiate a new call.
To release a new call and return to the held call

2. The original call rings back to station.
3. Lift the handset and continue with the original call.
To hold a new call and return to original call

PICKUP - GROUP [C-7] or TRUNK ANSWER FROM ANY STATION [T-8] features.
2. If the controlling user does not dial any further digits after the CALL HOLD code, removal of dial tone
will occur after 12 seconds; reorder tone is then applied for 30 seconds followed by muting of the station
set.
3. Calls will remain on hold until the controlling user either replaces the handset, causing the held call to ring
back, or flashes the switch hook and redials the Hold code to return to the original call.
