20
Enhanced operation
Once you enable Misoperation Alerting, calls are handled depending upon the
type of call placed on hold and the type of telephone (digital multiappearance,
analog single-line, or attendant console) in use when the misoperation occurs. The
following list describes the 3 call types that determine misoperation handling.
■ Call Type 1 — An outgoing public-network call is classified as Type 1
when answer supervision is received or when the trunk group’s Answer
Supervision Timer expires, even if the trunk is still ringing. An incoming
call is classified as Type 1 when it is answered.
■ Call Type 2 — An incoming external-public-network call is classified as
Type 2 before it is answered. A misoperation cannot occur with a Type 2
call because an unanswered incoming call cannot be placed on hold
without first being answered.
■ Call Type 3 — All internal calls, conference calls, and tie-trunk calls are
classified as Type 3.
Analog terminal misoperation
The following 2 scenarios describe typical misoperations on an analog terminal.
Scenario 1.
1. While connected to an incoming external call (Type 1), an analog-terminal
user flashes to transfer the call to another terminal.
2. The user hears dial tone, dials an invalid extension, then hears intercept
tone.
3. When the user hangs up, the call re-alerts the user for 15 seconds and
eventually routes to the attendant.
Scenario 2.
1. While connected to an incoming external call (Type 1), an analog station
user flashes to place the call on hold while calling another extension.
2. The user hears dial tone and dials the CAS Remote Hold/Answer
Hold/unhold access code.
3. The user dials an extension and talks with the user at the extension and
hangs up.
4. A misoperation occurs because the first call is still left on hold.
5. The terminal is alerted for 15 seconds and the call routes to an attendant.
6. If the first call is not answered before the timer expires, the call drops.
