The system uses a single, short tone, called a redirect tone, to inform an internal calling party (including incoming trunk calls from DCS and QSIG-VALU trunk groups) that the system is redirecting a call to coverage. The redirect tone is followed by an optional period of silence, called the Caller Response Interval. During this interval, the calling party has time to decide whether to:
  • Disconnect
  • Activate Priority Calling (this overrides coverage and re-rings the called party with a special ringing tone)
  • Activate Leave Word Calling (LWC)
  • Activate Automatic Callback
  • Activate Go to Cover (this cancels the remaining Caller Response Interval and rings the first available coverage point)
Note that each of the above features except Go To Cover is available both locally on a single server, as well as over DCS and QSIG-VALU. The ability for the calling party to hear the redirect tone does not require the optional feature DCS Call Coverage; it is part of basic DCS.
Administer the redirect tone on page 2 of the Tone Generation screen (change tone-generation) by selecting
Note:
If the majority of the calls on your system go directly to voice mail without first covering to another party, and if features such as Leave Word Calling, Automatic Callback, Go To Cover, and Priority Calling are rarely used, it is advisable to reduce the length of this interval from its default value of 4 seconds, since this timer increases the delay before the voice mail system answers the call.
