Station Message Detail Recording (SMDR) S-10
Interactions (cont’d)
5. LEAST-COST ROUTING-3/6-DIGIT [L-5]: SMDR will record the digits sent rather than the digits
dialed.
6. The destination station is recorded on SMDR for the following features:
CALL FORWARDING [C-2, 3, 5]
CALL PICKUP [C-7, 30]
7. CALL FORWARDING-INTERCEPT [C-25]: An incoming trunk call responds to Call Forwarding-
Intercept to the Attendant Console. SMDR records the call as if it is a direct call to the Attendant Console.
8. NIGHT CONNECTION-FIXED/FLEXIBLE: Calls terminated to these stations are recorded on SMDR. 
9. OUTGOING TRUNK QUEUING [O-2]: SMDR records the outgoing call when the system recalls the
user and the digits are sent, not when the trunk is queued.
10. REMOTE ACCESS TO SYSTEM [R-2]: The incoming route and trunk number is recorded as the calling
party. If FORCED ACCOUNT CODE [F-7] is used, it will be recorded on SMDR. REMOTE ACCESS
TO SYSTEM via a DID will not record FORCED ACCOUNT CODE on SMDR.
11. TRUNK-TO-TRUNK CONNECTION [T-10] and TIE LINE ACCESS [T-3]: SMDR records an
incoming TIE Line that uses TRUNK-TO-TRUNK CONNECTION to make an outgoing call. The TIE
Line route and trunk number is recorded as the calling party. The outgoing route is programmed for SMDR
in ARTD, not the incoming TIE Line route. 
12. CALL WAITING-TERMINATING [C-12]: SMDR will begin recording the call when the call is
answered, not when a Call Waiting Tone is heard.
13. ADD ON CONFERENCE - 8 PARTY [A-121]: When output of the billing information for the C.O. call
and station-to-station call is not restricted on either station or port for the calling/called party, the billing
information for the station-to-station call is output to SMDR.

S-13 Step Call
S-13 Step Call
General Description
This feature allows the Attendant or user, upon calling a busy station, to call an idle station by dialing an additional
digit. This feature will operate only if the number of the idle station is identical to that of the busy station in all
respects, except the last digit.
Operating Procedure
1. The dialed station (220) is busy.
2. Dial “5” (or any digit between 0 and 9).
3. If Station 225 is idle, the call will be connected there.
Service Conditions 
1. This feature can be provided for all stations and the Attendant Console(s).
2. STEP CALLING can be in any order, 0-9 or 9-0.
3. If the second selected station is also busy, STEP CALLING can continue until a station rings.
4. If a station is set for any type of CALL FORWARDING (ALL CALLS, BUSY LINE NO ANSWER [C-
2, 3, 5]), the call forwarding will take effect.
5. CALL FORWARDING - ALL CALLS/BUSY LINE [C-2, 5]: The activation of a call forwarding feature
by the called station can cause a STEP CALL to be completed to a station other than the dialed station.
6. CONSULTATION HOLD - ALL CALLS [C-17]: STEP CALL can be activated when a busy tone is
returned on a Consultation Hold attempt.
7. The STEP CALL feature is not operational for trunk incoming calls to PBX stations.
Note:STM:2 and STS:6 should be assigned as 1 by ASTD command, to restrict Step Call on DID.
8. A STEP CALL to a station in LINE LOCKOUT [L-3] or maintenance busy state will result in a reorder
tone.
Interactions 
1. A STEP CALL can search through an entire group to find an idle station. 
2. CALL FORWARDING [C-2, 3, 5]: STEP CALL will respond according to the numbering scheme of the
dialed station. Station A (7526) call forwards his phone to Station B (7128). Station B is busy. The calling
station dials 7526 and receives busy tone. The calling station then dials 2. The call terminates at 7522.
3. CONSULTATION HOLD-ALL CALLS [C-17]: STEP CALL can be used when encountering a busy
station via CONSULTATION HOLD.
4. LINE LOCKOUT [L-3]: A STEP CALL to a station in LINE LOCKOUT [L-3] results in reorder tone.
Another digit can be dialed to reach an idle station.
5. When STEP CALL [S-13] is used after LAST NUMBER CALL [L-6, 6D] service with the access code,
the destination of STEP CALL is changed depending on the access code of the LAST NUMBER
CALLED [L-6, 6D] service because the PBX recognizes the access code of LAST NUMBER CALLED
as the telephone number. In other words, the target number for STEP CALL is not the telephone number
dialed before LAST NUMBER CALLED, but the number dialed as the LAST NUMBER CALLED access
code. For example:
a.) Station A places a call to Station B (4000) by dialing “300”, which is the access code of LAST
NUMBER CALLED.

Rotary type phones cannot store a pause. A pause lasts 2.8 seconds.
12. It is not necessary to erase a stored number in order to store another number. The second number replaces
the first.
13. When a caller places a call via Outgoing Call Alternative (OGCA), and when the first outgoing route and
the station setting SPEED CALLING - STATION are restricted, this service cannot be set. In this case,
the service can be set via the following procedure:
a.) assign a dummy route,
b.) clear the restriction between the dummy route and all the stations,
c.) assign the dummy route as the first route of OGCA. 
Interactions
1. Blocks are not assigned sequentially (1-100), but are assigned as a quantity of blocks in the AISA
command. These quantities will never exceed the value of 10. 
2. If one block is assigned, the Abbreviated Call Code will be digits 0-9. If two blocks are assigned, the
Abbreviated Call Code will be digits 00 - 19. If three blocks are assigned, the Abbreviated Call Code will
be digits 00 - 29, and so on, to a maximum of 10 blocks with Abbreviated Call Codes 00 - 99.
3. Only the Primary Station will be allowed to use the SPEED CALLING-ASSIGN access code. When
assigning the abbreviated SPEED CALLING access code and number, a delay of 6-8 seconds will occur
until service set tone is returned.
4. Only those stations assigned as Secondary stations are considered to be members of the SPEED
CALLING-GROUP.
5. Stations of a SPEED CALLING-GROUP (INDIVIDUAL) must be in the same Module Group (MG).
Error 0238, “MG number of MY-Line/Primary station mismatch” is displayed.
6. SPEED CALLING-INDIVIDUAL requires the assignment of senders, route 905. See UNIVERSAL
