C-99 Call Transfer - All Calls - PRI
C-99 Call Transfer - All Calls - PRI
General Description
This feature permits a user to transfer incoming or outgoing ISDN calls to another station without Attendant
assistance.
Operating Procedure
To transfer a call in progress
1. While connected with the first party, press the switchhook; receive special dial tone.
2. Dial the third party; receive ringback tone.
3. The user can then either:
a.) Hang up before the third party answers. The first and third parties are connected when third party
answers.
b.) Wait for third party to answer and announce the transfer while keeping the first party in a
CONSULTATION HOLD - ALL CALLS - PRI [C-100] condition. When the user hangs up, the
first and third parties are automatically connected.
Service Conditions
1. The station performing the CALL TRANSFER - ALL CALLS can drop off the connection before the
called party answers. If the called station does not answer within the predetermined time, ringing is
returned to the transferring station. See VARIABLE TIMING PARAMETERS [V-1] feature for
additional timing choices.
2. In the case of outgoing calls (no answer supervision), this feature can be activated only after 18 seconds
have elapsed since the last digit dialed.
3. Outgoing calls with answer supervision may be transferred immediately after call is answered (no time
delay).
4. The THREE-WAY CALLING [T-2] feature can comprise not more than three parties on one connection.
The three parties connected can be as follows:
a.) Two stations and one trunk
b.) One station and two trunks
5. The maximum number of simultaneous THREE-WAY CALLING [T-2] connections per system is
dependent on the quantity of conference-function circuits equipped (traffic engineered). The conference
function is included in the INT and TSW-INT cards.
6. When transferring a call from a station or trunk (second party) to another station (third party), the control
station can transfer the call during ringing. When the control station goes on-hook, the station or trunk on
hold is connected to the third party’s connection and hears ringback tone. A variable timer is set when the
controlling station goes on-hook. If the timer times out before the third party answers, the control station
is rung back. When transferring a call from a loop start trunk, the trunk is disconnected if the timer times
out before the third party answers.
7. When transferring a call from a trunk or station (second party) to a trunk or station (third party), the control
station cannot answer the call during ringing. If the control station goes on-hook, during the ringing state,
the station or trunk (second party) is not connected to the third party’s line, and the controlling station will
be rung back again.
