The PSTN line monitor is accomplished through monitoring the loop-break signal,
polarity reversal or busy tone. The value range of loop-break signal is:
0/100/200/
…
/1000 ms.

Call Operator (Call Attendant)
IG6600 supports one operator. Any extension can be designated as the operator
through system configuration.
One primary operator may be assigned in the system. The standard IP phone will serve
as the operator telephone. When assigned as operator, this extension supports general
system functions.
While the internal extension dials Operator Directory Number ("0" at default), or the
outside party dials "0" when Auto Attendant plays the welcome message, these calls will
be stored into Operator Queue. The Operator is First-In-First-Out to service these calls.
At the waiting time, the calling party will be on Music-On-Hold state.
A second (alternate) operator position may be designated for common sharing of
incoming operator calls during peak traffic period.

Call Restriction
IG6600 provides sophisticated monitoring of digits dialed on PSTN/IP Trunks. If a digit or
range of digits dialed on a Trunk line is inconsistent with the dialing extension
’
s COS, the
call is denied. This calling COS criteria can be applied to local calls, long distance calls,
and specific numbers that are considered allowed in areas where other numbers may be
restricted.
In the call restriction table, it provides the following programming items:
•
From/To
The allowed intervals are made up of a From and To entry which establish a
numeric range. For example, an entry of
“
From 1700
”
,
“
To 1800
”
would include
the following range of numbers as the leading: 1700, 1701, 1702,
…
1799, 1800.
Each From/To entry can be from 1 to 13 digits long and may contain any digit 0-9.
The
“
From
”
entry must be less than or equal to the
“
To
”
entry.Each From/To entry
can be from 1 to 13 digits long and may contain any digit 0-9, or X (X representing
any digit). The :From
”
entry must be less than or equal to the
“
To
”
entry.
•
Trunk Access
IG6600 checks the field only when a call matches the associated allowed
interval. If the field is set to
“
Y
”
, the entry is valid when the trunk is accessed
previously. If the field is set to
“
N
”
, the trunk isn
’
t accessed previously. The trunk
will be accessed through Call Routing Table. If he option is set to
“
YN
”
, the entry
is valid no matter the trunk is accessed or not previously.
•
COS
The COS setting is defined by the allowed intervals.
“
Y
”
allows an extension with
the COS or higher priority to dial the number(s) specified in that range.
