The figure below shows an example of a configuration setup of two communicating FXS
devices. Phones ā101ā and '102' are connected to the first two channels of device with IP
address 10.33.24.18; phone ā120ā is connected to the first channel of device 10.33.24.14.
The configuration in the 'Endpoint Phone Number Table' and āTel to IP Routing Tableā
pages (refer to the figure below) enables calls to be made between these two devices as
well as between phones connected to the same device.
To make a call between the two devices, off-hook phone ā101ā, and at the dial tone, dial
'120'. To make a call between the two phones connected to device 10.33.24.18, off-hook
phone '101', and at the dial tone, dial '102' (or vice versa).
Notes:
⢠The prefixes entered in the āTel to IP Routing Tableā
ā¢
must differentiate the
devices from each other to ensure correct routing. In the example, using
the first digit (i.e., 1) doesnāt differentiate the devices, therefore, two digits
of the phone number are used.
To enable phones connected to the same device to communicate with
each other, define in the āTel to IP Routing Tableā
the IP address and
corresponding phone numbers of the device itself.
