8.12 Configuration Examples
8.12.1 Establishing a Call between Two Gateways
After you’ve installed and set up the MediaPack, you can ensure that it functions as
expected by establishing a call between it and another gateway. This section exemplifies
how to configure two 8-port MediaPack FXS SIP gateways to establish a call. After
configuration, you can make calls between telephones connected to a single MediaPack
gateway or between the two MediaPack gateways.
In the following example, the IP address of the first gateway is 10.2.37.10 and its endpoint
numbers are 101 to 108. The IP address of the second gateway is 10.2.37.20 and its
endpoint numbers are 201 to 208.
In this example, a SIP Proxy is not used. Internal call routing is performed using the
internal ‘Tel to IP Routing’ table.

To configure the two gateways, take these 4 steps:
1. For the first MediaPack gateway (10.2.37.10), in the ‘Endpoint Phone Numbers’
screen, assign the phone numbers 101 to 108 for the gateway’s endpoints.
2. For the second MediaPack gateway (10.2.37.20), in the ‘Endpoint Phone Numbers’
screen, assign the phone numbers 201 to 208 for the gateway’s endpoints.
3. Configure the following settings for both gateways:
In the ‘Tel to IP Routing’ screen, in the first row, enter 10 in the ‘Destination Phone
Prefix’ field and enter the IP address of the first gateway (10.2.37.10) in the field ‘IP
Address’. In the second row, enter 20 and the IP address of the second gateway
(10.2.37.20) respectively. These settings enable the routing (from both gateways) of
outgoing TelÆIP calls that start with 10 to the first gateway and calls that start with 20
to the second gateway.
4. Make a call. Pick up the phone connected to port #1 of the first MediaPack and dial
102 (to the phone connected to port #2 of the same gateway). Listen out for progress
tones at the calling endpoint and for ringing tone at the called endpoint. Answer the
called endpoint, speak into the calling endpoint, and check the voice quality. Dial 201
from the phone connected to port #1 of the first MediaPack gateway; the phone
connected to port #1 of the second MediaPack rings. Answer the call and check the
voice quality.
