Step 3: ETM® System Configuration
(
Does not apply to SS7 signaling links
)
To configure telephony settings
1.
In the
Span Configuration
dialog box, click the
Telephony
tab.
2.
In the
Country Code
box, type the country code for the country in
which the Appliance is located. By default, the country code is set to 1.
(U.S., North American Numbering Plan).
3.
In the
Local Area Code
box, type the area code where the Appliance
is installed. By default, the area code is set to 210 (San Antonio,
Texas).
4.
In the
Call Established Timeout
box, type the length of time after
the last digit is dialed until a call is marked as established. The default
is 20 seconds, which corresponds with the timeout value of most
telephone network switches. If your network differs, adjust this value
accordingly. This setting is used for outbound analog and T1 loop start
and ground start calls, which do not provide answer supervision.
5.
In the
Call Type Timeout
box, type the length of time the Span waits
after a call is established before first classifying a silent or
indistinguishable call as Voice. Call type timeout only applies to calls
where lack of activity on the line prevents the Span from determining
the call type. Setting this value too low can cause an excessive number
of call type changes. The default is 60 seconds.
6.
If SMDR is in use, in the
SMDR Timeout Period
box, type the
length of time the Span is to wait for an SMDR result from the
Management Server after a call ends. The default is 1 minute.
