Establishing a Call between Two Devices

This section provides an example on configuring two AudioCodes' devices with FXS
interfaces for establishing call communication. After configuration, you can make calls
between telephones connected to the same device and between the two devices.
This example assumes the following:
The IP address of the first device is 10.2.37.10 and its endpoint numbers are 101 to
104.
The IP address of the second device is 10.2.37.20 and its endpoint numbers are 201
to 204.
A SIP Proxy is not used. Internal call routing is performed using the device's 'Tel to IP
Routing'.
To configure the two devices for call communication:
1. For the first device (10.2.37.10), in the 'Endpoint Phone Number Table' page (see
Configuring Endpoint Phone Numbers on page 124), assign the phone numbers 101
to 104 to the device's endpoints.

2. For the second device (10.2.37.20), in the 'Endpoint Phone Number Table' page,
assign the phone numbers 201 to 204 to the device's endpoints.

3. Configure the following settings for both devices:
In the 'Tel to IP Routing' page (see ''Configuring Tel to IP Routing'' on page 138), add
the following routing rules:
a. In the first row, enter 10 for the destination phone prefix and enter 10.2.37.10 for
the destination IP address (i.e., IP address of the first device).
b. In the second row, enter 20 for the destination phone prefix and 10.2.37.20 for
the destination IP address (i.e., IP address of the second device).
These settings enable the routing (from both devices) of outgoing Tel-to-IP calls that
start with 10 to the first device and calls that start with 20 to the second device.
4. Make a call. Pick up the phone connected to port #1 of the first device and dial 102 (to
the phone connected to port #2 of the same device). Listen for progress tones at the
calling phone and for the ringing tone at the called phone. Answer the called phone,
speak into the calling phone, and check the voice quality. Dial 201 from the phone
connected to port #1 of the first device; the phone connected to port #1 of the second
device rings. Answer the call and check the voice quality.
