8.11 Configuration Examples
8.11.1 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 in order 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. Call routing is performed using the internal ‘Tel to IP
Routing’ table.
¾ To configure the two gateways, take these 4 steps:
1. Configure the following settings on the first MediaPack gateway (10.2.37.10):
¾ In the ‘Endpoint Phone Numbers’ screen, assign the phone numbers 101 to 108 for the
gateway’s endpoints.
2. Configure the following settings on the second MediaPack gateway (10.2.37.20):
¾ 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:
¾ 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, talk
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.
