Hold Disconnect Interval

DESCRIPTION

CONSIDERATIONS

Telephone company central offices use either a “short” (50 millisecond) or a “long” (450 millisecond) disconnect interval. Because most switching systems use a long interval, your MERLIN II system is factory-set for a long interval. If your telephone company uses a short interval or if your MERLIN II system has been reprogrammed, the disconnect intervals for your system may cause problems with held calls.

If your system has either of the following problems, the system administrator must change the Hold Disconnect Interval.

If a caller waiting on hold is disconnected, the disconnect interval setting of your MERLIN II system is shorter than the setting at your local telephone company’s central office.

If a caller waiting on hold hangs up, but the light next to that line button on voice terminals in your system continues to flash as if the call were still on hold, the disconnect interval setting of your MERLIN II system is longer than the setting at your local telephone company’s central office.
