Hold Disconnect Interval
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
ins). The hold disconnect interval applies to loop-start trunks connected to 400,
408, or 800 modules; it does not apply to emulated loop-start trurlks (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 the lines/trunks on
hold to be disconnected. See "Disconnect Signaling Reliability. "
For more information on Hold Interval Disconnect and Reliable and Unreliable
Disconnect, see the Feature Reference.
