12. OFF-HOOK VOICE ANNOUNCE 
(OHVA) 
12.1 When a called 24-line keyset is busy, the caller 
can use the off-hook voice announce (OHVA) fea- 
ture (if enabled). This feature allows an intercom 
caller (either single-line or keyset) to establish voice 
contact with a 24-line keyset user, even though the 
user already has a call in progress on the handset. The 
called keyset user can then talk freely on either con- 
nection, using the handset for the original call or the 
speakerphone for the OHVA intercom call. 
12.2 The OHVA feature requires special installa- 
tion and programming (refer to INSTALLATION, 
page 3-14, and PROGRAMMING, page 5-49, for 
complete details). When the system is initialized, this 
feature is disabled. Once the OHVA feature is en- 
abled system wide (and the appropriate installation 
procedures have been performed), each individual 
24-line keyset can be allowed or disallowed frompluc- 
ing and/or receiving OHVA calls. Also, each 24-line 
keyset without a secondary voice path, 1Zline keyset, 
and single-line set can be allowed or disallowed from 
placing OHVA calls. (Single-line sets and 1Zline key- 
sets cannot receive OHVA calls because they do not 
have secondary voice path circuitry.) 
12.3 For example, you may want to allow all atten- 
dants to place, but not receive, OHVA calls, while all 
other stations are allowed to receive, but not place, 
OHVA calls. Any combination is available through 
system and station programming. 
12.4 OHVA calls cannot be processed if the second- 
ary voice path or the speakerphone of the called 
24-line keyset is not available. This occurs when the 
keyset has a different OHVA call in progress, has an 
active data call in progress, is on an active handsfree 
intercom or outside call, has handsfree disabled, has a 
headset enabled, or is in do-not-disturb. Also, OHVA 
calls are not possible if the caller is placing a forced 
private intercom call. 
12.5 
TO PLACE AN OFF-HOOK VOICE ANNOUNCE CALL: 
(1) When an intercom call is placed to a busy 
24&e keyset, do not hang up. You hear busy 
signals until the camp-on timer and the OHVA 
screening timer expire. 
(If you hear music after 
the camp-on timer expires, conditions for an 
OHVA call were not met and you are camped- 
on. See paragraph 10.14.) 
(2) When the OHVA screening timer expires (and 
if the keyset’s secondary voice path is avail- 
able), you are automatically connected to the 
called party’s speakerphone. 
12.6 
TO PLACE AN IMMEDIATE OFF-HOOK VOICE 
ANNOUNCE CALL (KEYSETS EQUIPPED WITH DSSIBLF 
UNITS ONLY): 
NOTE: This method can only be used if the database 
has been programmed to allow keysets with attached 
DSS/BLF Units to bypass the camp-on and OHVA 
screening timers. See page 5-24 in PROGRAM- 
MING. 
(1) When an intercom call is placed (using the 
DSS/BLF key) to a busy 24-line keyset, do not 
hang up. 
(2) Press the DSS/BLF key for that keyset again. 
If the keyset’s secondary voice path is avail- 
able, you are immediately connected and may 
speak. 
12.7 
TO RECEIVE AN OFF-HOOK VOICE ANNOUNCE 
CALL (OHVA-EQUIPPED 24-LINE KEYSETS ONLY):‘ 
(1) While on a call using the handset, you hear a 
camp-on tone (display shows CALL 
ANNOUNCE FROM XXX). Do nothing. 
When the OHVA screening timer expires, you 
hear a double tone (display shows INTER- 
COM CALL FROM,XXX). You are con- 
nected with the intercom caller via the speak- 
erphone. Your original call remains connected 
on the handset. 
(2) 
To terminate the OHVA call: Press the lit 
SPKR key or have the OHVA caller hang up. 
If you terminate the original call by hanging up 
the handset, you remain connected to the 
OHVA call in the handsfree intercom mode. 
12.8 
TO BLOCKAN OFF-HOOK VOICE ANNOUNCE CALL 
(OWA-EQUIPPED 24-LINE KEYSETS ONLY): 
(1) 
(2) 
While on a call using the handset, you hear a 
camp-on tone (display shows 
CALL 
ANNOUNCE FROM XXX). To cause the in- 
tercom call to camp on, press the SPKR or 
DND key. The IC key flashes. 
If you wish to send do-not-disturb signals to the 
camped-on call, 
press the DND key two more 
times if the DND key was used in step 1, 
or 
press the DND key once if the SPKR key was 
used in step 1.

13. OUTSIDE CALLS 
13.1 When a line is selected for receiving or placing 
an outside call, a voice channel is seized and cannot 
be used by any other station (unless privacy release is 
enabled or the conferencing feature is used). If the 
desired line is busy, the station user can camp on or 
request a callback (queue). 
13.2 Other features that apply to both outside and 
intercom calls are discussed later in this section of the 
manual. They include placing calls on hold, call wait- 
ing, call transfer, reverse transfer, conferencing, and 
call forwarding. Refer to page 4-25 for an explanation 
of outgoing-access, allowed-answer, and ring-in as- 
signments. Refer to page 4-29 for an explanation of 
line groups, auto lines, and the use of the automatic 
line answer and automatic line select feature codes. 
Refer to page 4-35 for an explanation of using the 
OVER key on 1Zline keysets to access calls on out- 
of-range lines.

CALLS (3) 
Placing Outside Calls 
13.3 
TO PLACE AN OUTSIDE CALL: 
NOTE: When placing a call, begin dialing before the 
dial initiation timer expires. If the timer expires, the 
system drops the line connection and sends repeating 
reorder tones. This prevents a line from being tied up 
accidentally. 
(1) Lift the handset. (Keyset users, see paragraph 
13.7 for on-hook dialing instructions.) 
(2) Select an outgoing line, using one of the meth- 
ods below. The associated line key or the 
OVER key flashes slowly.

You hear one of the following signals: 
Outside dial tone: Go to the next step. The 
associated line key (ii one exists) flashes 
slowly. 
If SCOS is associated with account 
codes (system-wide option), and you wish to 
use your usual SCOS while at another station, 
press SPCL and enter the optional account 
code feature code (390), then enter your 
account code. 
Single progress tone: Enter a forced account 
code. The display shows ACcT#. You hear 
a single progress tone and then outside dial 
tone when the code is accepted. The asso- 
ciated line key or the OVER key flashes 
slowly. 
If SCOS is associated with account 
codes (system-wide option), 
your usual 
SCOS is now in effect. Go to the next step. 
Repeating reorder tones: You are restricted 
from the line chosen; choose another line. 
Or, you are restricted to using ARS only; 
try again using ARS (refer to

D. ACCOUNT CODES 
13.16 
There are three types of account codes in the 
GMX-48 System. All account codes are assigned the 
same character length (4-8 characters) in database 
programming. The three types are as follows: 
’ 
Standard account codes automatically appear in 
the SMDR report (if programmed) to identify the 
station that answered or initiated the call. Up to 
32 standard account codes can be defined for the 
system. Stations can then be assigned one of the 
32 account codes during station programming. 
Forced account codes are programmed on a sta- 
tion-by-station basis. If required, a forced account 
code must be entered before the station user is 
given access to a selected outgoing line (refer to 
paragraph 13.3 for procedures). Up to 120 forced 
account codes can be assigned in the database pro- 
gramming. The account code entered by the sta- 
tion user must match any one of the programmed 
forced account codes before line access is granted. 
The forced account code appears in the SMDR 
account code field. 
Optional account codes are used to identify calls 
to and from customers for billing purposes. They 
can be entered at any time during a call. These 
user-defined codes are not pre-programmed, but 
must be the same length as the standard and 
forced account codes. If entered, optional account 
codes are printed in the SAR and the SMDR re- 
port for that call in place of standard or forced 
codes that may have been used. 
13.17 Forced and optional account codes can be 
programmed to be associated with station class of ser- 
vice (SCOS). This permits a user to place a call from 
any station using his account code and his usual 
SCOS. When the account code is entered, either as a 
forced account code (as described in paragraph 13.3) 
Page 4-55  
						

							FEATURES 
INTER-TEL PRACTICES 
Issue 2, May 1990 
GMX.48 INSTALLATION & MAINTENANCE 
or as an optional account code (using the procedure 
on the next page), the system checks the associated 
SCOS and applies it to the call being made. When the 
call is completed, the programmed SCOS for the sta- 
tion goes back into effect. 
13.18 
TO ENTER AN OPTIONAL ACCOUNT CODE WHILE 
ON AN OUTSIDE CALL: 
(1) Keyset: Press the SPCL key and enter the op- 
tional account code feature code (390). (Dis- 
play shows ACCT#.) The outside party does 
not hear you enter the code. 
Single-Line Set: Press the FLASH key and en- 
ter the optional account code feature code 
(2) 
(390). The call is placed on hold while the ac- 
count code is being entered. . . 
Enter the account code using the keypad; key- 
set users may press a SPD/BLF key to enter an 
account code number that has been stored in 
an outside speed-dial number location. 
(Display shows numbers.) You hear a single 
progress tone when the code is accepted. 
Single-line users are reconnected when the 
system accepts the account code. (If an ac- 
count code is entered that has fewer than the 
programmed number of digits, single-line 
users will return to the call after the short in- 
terdigit timer expires.)

14. PLACING CALLS ON HOLD 
14.1 There are several ways to place intercom and 
outside calls on hold. The party on hold hears music. 
Individual hold places the call on hold at only one 
station. It can then be picked up directly at that 
station or it can be picked up at another station us- 
ing the reverse transfer feature. 
System hold places the call on hold at all stations. 
It can then be picked up directly at any keyset sta- 
tion that shows a fluttering line key for the call. 
(Single-line set users cannot place calls on system 
hold or pick up calls already on system hold.) 
Users with 12-line keysets cannot place calls on 
out-of-range lines (13-24) on system hold. Also, 
calls on out-of-range lines that are placed on sys- 
tem hold by 24-line keyset users cannot be picked 
up by 1Zline keyset users. Intercom calls cannot 
be placed on system hold. If this feature code is 
used on conference calls, the callers are placed on 
individual hold. 
Consultation hold allows a single-line set user to 
pause during a call, use other system features, and 
then return to the caller by pressing the FLASH 
key (hookflashing). If a single-line set user 
attempts to hang up after placing a call on consul- 
tation hold, the call immediately recalls the sta- 
tion. 
Call splitting allows a station user to place two or 
more calls on individual hold and then easily split 
between the calls. 
Skate-to-hold, if enabled in the database, allows 
keyset users to’place calls on individual hold when 
another line key or the IC key is pressed during a 
call (instead of pressing the HOLD key). The sys- 
tem is initialized to disconnect calls when another 
key is pressed (skate-to-disconnect). 
14.2 If an outside call remains on hold until the hold 
timer expires, it recalls the station. If it is still unan- 
swered when the recall timer expires, it recalls the 
station’s attendant. If the attendant does not answer 
the recall before the abandoned recall timer expires, 
the call is disconnected by the system. (If the station 
does not have an attendant, or the system is in night 
mode, the call recalls the station that placed it on hold until the abandoned recall timer expires and the call 
is disconnected.) Intercom calls that are placed on 
hold do not recall the attendant. 
NOTE: Keyset users can avoid the hold timer by mut- 
ing the microphone during a call instead of placing 
the call on hold (if thisis done, the caller will not hear 
music-on-hold and the call will not recall the station). 
143 A programming option can be enabled that will 
change the system hold flash rate to a, continuous 
9601PM to differentiate it from the 60/96OIPM flutter 
used for individual hold. If the option is not enabled, 
both hold types use the 60196OIPM flutter.

B. SYSTEM HOLD 
NOTE: 
Intercom calls cannot be placed on system 
hold. If you attempt to do so, you will hear reorder 
tones. Users with 12line keysets cannot place calls on 
out-of-range lines on system hold. Also, if an out-of- 
range C.O. line is placed on system hold, the call can 
only be picked up at keysets that have a fluttering line 
key for the call. The ANS and OVER keys cannot be 
used to access an out-of-range line that is on system 
hold. (Single-line set users cannot place calls on sys- 
tem hold or pick up calls already on system hold.) (3) Return to the caller on hold by pressing the
