Description
in Round-robin order.
Least cost routing
: Analog trunks are selected for local calls, and IP trunks are
selected for long distance/international calls. The device determines the long
distance/international calls based on the prefix. For example: If the long distance
call prefix is 0 and the international call prefix is 00, an IP trunk is selected for the
calls made with the numbers starting with "0" or "00". An analog trunk is selected
for local calls. If the IP trunk is not activated or a network failure occurs, an analog
trunk is also selected for calls made with the numbers starting with "0" or "00".
Note:
If a long distance/international call is made with all IP trunks occupied, the
following announcement will be played: All circuits are busy. Please try your call
again later.
Route:
The routing table rules are used to make the call to the PSTN.
Prefix
The user can make an outbound call with a routing method identified by the prefix
configured here. For example, if the prefix for
Sequential hunting for IP trunk
is
9, the device will make sequential hunting over IP trunk when dialing the number
starting with 9.
Note:
The parameter can be configured only when the
Dialing method for outbound
calls
is
Outbound dialing with prefix
.
To avoid collision, the prefix must be different from extension number, hunting
group number, number to reach the operator, feature access code, and other
outbound call prefixes.
Secondary
dial tone
After the extension user dials the prefix, the device prompts the user to dial the
called number with secondary dial tone.
Note:
Applicable only when the
Dialing method for outbound calls
is
Outbound
dialing with prefix
.
Trunk
Specify the corresponding trunk numbers for the outbound group of analog trunks
and IP trunks. Select the trunk numbers directly or enter them manually. The trunk
numbers must be separated by ",".
Step 4
To verify your progress, place an outbound call to an external cell phone or other phone with caller
ID, and confirm that the specified line was used for the call.
4.2 Configuring the ATA
4.2.1
Configuring the ATA General Settings
There are several settings that are recommended to ensure good performance on your voice network.
Complete this procedure before performing any other configuration tasks.
Step 1
You need to localize the system
configuration by modifying some parameters according to your
regional preference, including time zone, Caller ID detection mode, call progress tones and digit
map.
Step 2
It is recommended to assign a static IP address for your ATA.
Method 1:
On ATA interface, go to
Basic > Network
page to setup Static IP address on WAN
