18.8.3 Establishing a Call between Two Devices

This section provides an example on configuring two AudioCodes' devices with FXS
interfaces for establishing call communication. This setup enables the establishment of
calls between telephones connected to the same device, and between the two devices.
This example assumes the following:

IP address of the first device is 10.2.37.10 and its endpoint numbers are 101 to 104.

IP address of the second device is 10.2.37.20 and its endpoint numbers are 201 to
204.

SIP Proxy is not used. Internal call routing is performed using the device's Outbound
IP Routing Table.

To configure the two devices for call communication:
1. For the first device (10.2.37.10), in the Trunk Group Table page (see Configuring
Trunk Group Table on page
device's endpoints.
2. For the second device (10.2.37.20), in the Trunk Group Table page, assign the phone
numbers 201 to 204 to the device's endpoints.
3. Configure the following for both devices:
In the Outbound IP Routing Table page (see 'Configuring Outbound IP Routing Table'
on page 271), 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.
