Hold Disconnect Interval 3
Use this procedure to specify the number of milliseconds before a loop-start
line/trunk is released when a caller on hold hangs up and abandons the call. This
can be specified as either a long interval (450 ms) or a short interval (50 ms). The
hold disconnect interval applies to loop-start trunks; it does not apply to emulated
loop-start trunks (T1 facility).
NOTES:
1. If the disconnect interval is longer than the telephone company setting,
the line is not released when a caller on hold hangs up.
2. Do not program a short interval unless the local telephone company’s
central office is the crossbar type.
3. Do not program a reliable disconnect for lines/trunks with a short hold
disconnect interval. This can cause active calls as well as lines/trunks on
hold to be disconnected. See “Disconnect Signaling Reliability” on page
61.
For more information on Hold Interval Disconnect and Reliable and Unreliable
Disconnect, see the
Feature Reference.
