Mediant 2000 SIP

Enable the DMZ (Demilitarized Zone) configuration on the residential router for the LAN port where the Mediant 2000 gateway is connected. This enables unknown packets to be routed to the DMZ port.

2.Under ‘SIP Parameters’, enter the Mediant 2000 domain name in the field ‘Gateway Name’. If the field is not specified, the Mediant 2000 IP address is used instead (default).

3.When working with a Proxy server, set ‘Working with Proxy’ field to ‘Yes’ and enter the IP address of the primary Proxy server in the field ‘Proxy IP address’. When no Proxy is used, the internal routing table is used to route the calls.

4.Enter the Proxy name in the field ‘Proxy Name’. If Proxy name is used, it replaces the Proxy IP address in all SIP messages. This means that messages is still sent to the physical Proxy IP address but the SIP URI contains the Proxy name instead.

5.Configure ‘Enable Registration’ to ‘Yes’ or ‘No’:

‘No’ = the Mediant 2000 does not register to a Proxy server/Registrar (default).

‘Yes’ = the Mediant 2000 registers to a Proxy server/Registrar at power up and every ‘Registration Time’ seconds. For detailed information on the parameter ‘Registration Time’, refer to Table 6-3on page 100.

6.Select the coder (i.e., vocoder) that best suits your VoIP system requirements. The default coder is: G.7231 30 msec. To program the entire list of coders you want the Mediant 2000 to use, click the button on the left side of the ‘1st Coder’ field; the drop-down lists for the 2nd to 5th coders appear. Select coders according to your system requirements. Note that coders higher on the list are preferred and take precedence over coders lower on the list.

Note: The preferred coder is the coder that the Mediant 2000 uses as a first choice for all connections. If the far end gateway does not use this coder, the Mediant 2000 negotiates with the far end gateway to select a coder that both sides can use.

7.To program the Tel to IP Routing Table, press the arrow button next to ‘Tel to IP Routing Table’. For information on how to configure the Tel to IP Routing Table, refer to Section 5.8.4.1 on page 49.

8.To program the E1/T1 B-channels, press the arrow button next to ‘Trunk Group Table’. For information on how to configure the Trunk Group Table, refer to Section 5.8.6 on page 58.

9.Click the Reset button and click OK in the prompt; The Mediant 2000 applies the changes and restarts, taking approximately 3 minutes to complete. When the Mediant 2000 has finished restarting, the Ready and LAN LEDs on the front panel are lit green.

10.After the gateway was reset, access the Advanced Configuration>Trunk Settings page, and select the gateway’s E1/T1 protocol type and Framing method that best suits your system requirements. Note that for E1 spans, the framing method must always be set to ‘Extended Super Frame’. For information on how to configure the Trunk Settings, refer to Section 5.9.3 on page 66.

You are now ready to start using the gateway. To prevent unauthorized access to the Mediant 2000, it is recommended that you change the username and password that are used to access

the Web Interface. Refer to Section 5.9.7 on page 71 for details on how to change the username and password.

Tip: Once the gateway is configured correctly back up your settings by making a copy of the VoIP gateway configuration (ini file) and store it in a directory on your PC. This saved file can be used to restore configuration settings at a future time. For information on backing up and restoring the gateway’s configuration, refer to Section 5.9.5 on page 69.
