Lines on Hold, no
one there. System
Programming If the customer complains of seeing
many holding lines, and when accessed
no one is on the other end, calls may be
left in an abandoned state.
Outside caller
abandons call If the serving Central Office (Telco)
provides disconnect supervision:
† The KSU should be programmed (on
a per CO line basis) to recognize an
abandoned call (default).
† When the outside holding party
hangs up, the CO line interface
detects change in CO voltage for the
associated line.
† The KSU then removes the inside
Hold indication at all telephones and
restores the line to idle.
User error Auto Hold Allow may be enabled at a
station that is unsure of the proper
operation of this feature.
† If so, insure that inside users do not
accidentally place calls on Hold while
skipping from one CO line to
another, refer to the Key telephone
User Guide.
† By programming Auto Hold Deny
(code F94) at the abusing stations,
incoming CO lines will not be
accidentally placed on Hold.
