Installation Manual 3. Configuring the Device
3.3 Example of Enabling Channels and Configuring Call
Routing
This section provides an example for enabling the device's channels and for configuring Tel
(PSTN) to IP call routing. This includes assigning the channels a telephone number and
routing calls (with a dialed number of 10 as its prefix) made from these channels to a
specific IP destination (e.g., IP address 10.33.24.14).
¾ To enable channels and configure call routing, take these 2 steps:
1. Assign telephone numbers to endpoints, by performing the following:
a. Open the 'Endpoint Phone Number Table' page (Configuration tab > Protocol
Configuration menu > Endpoint Number submenu > Endpoint Phone
Number).
Figure 3-3: Assigning Phone Numbers in the Endpoint Phone Number Table Page
b. In the 'Channel(s)' column, enter 1-8 (i.e., channels 1 through 8), and then in the
'Phone Number' column, enter the phone number (e.g., 101) for the first channel.
Phone numbers 102, 103, 104 and so on are sequentially assigned to subsequent
channels (i.e., 2 through 8).
c. Click Submit.
2. Configure routing for telephone calls from the device (i.e., Tel) to an IP destination
(i.e., IP address):
a. Open the ‘Tel to IP Routing’ page (Configuration tab > Protocol Configuration
menu > Routing Tables submenu > Tel to IP Routing).
Figure 3-4: Defining Tel-to-IP Call Routing in the Tel to IP Routing Page
b. In the 'Dest. Phone Prefix' column, enter 10 (i.e., prefix of dialed number).
c. In the 'Source Phone Prefix' column, enter the prefix of the channel's telephone
number defined in Step 1.
d. In the 'Dest. IP Address' column, enter 10.33.24.14 (i.e., calls are sent to this IP
address).
e. Click Submit.
Therefore, any call whose dialed number prefix matches the value in the 'Dest. Phone
Prefix’ column (i.e., 10) and whose source phone number prefix matches the value in
the ‘Source Phone Prefix‘ column is sent to the IP address defined in the ‘Dest. IP
Address’ column.
