Ensure that you have created the extension that you wish to use with the phone in 3CX Phone System first. Take note of the Extension Number, the Authentication ID, and the Authentication password that you have entered for this extension.
-
Connect the Aastra 9133i or 480i phone to the network and mains power supply. The phone will boot up, and providing you have DHCP installed on your network, will obtain an IP. To find the IP, using the phone keypad, go to options/phone status (option 11)/network port 1 and view its IP address.
-
Now you can access the phone’s web configuration page by going to http://x.x.x.x where x.x.x.x is the IP address of the phone from step 2.
-
The factory default username and password for accessing web configuration on Aastra phones is “Admin” and “22222”. In “Advanced Settings” then “Network” tab you can see that DHCP is enabled by default - configure this according to preference (refer to screenshot 1).

-
Next step is to configure the “Global SIP” settings. You will only need to configure the section labeled “Basic SIP Network Settings” in this page (refer to screenshot 2).
a. Set the “Proxy server” field to the IP address or FQDN of the server on which
the 3CX Phone System is installed.
b. Set the “proxy port” to 5060. Please note that if the SIP port has been changed
from the default on the 3CX Phone System (in General Settings), this value must
be changed accordingly.
c. Set the “Registrar server” and “Registrar port” to the same values as in steps
a and b.
d. Set the Registration period to a value suitable for your company. For testing
purposes you may want to use 60 seconds, but once configuration is tested a larger
value would be more appropriate to limit unnecessary network traffic. A good setting
for general use could be 3600 seconds (1 hour).

Set “authentication name” as “password” to the same values you have configured in 3CX phone system as “Authentication ID” and “Authentication password”.

After the phone has rebooted, switch to the 3CX Phone System Management Console, and click on the Phone System -> “Line Status” (This is the default page). In the section “Extensions”, the phone’s extension will be listed with a green status light.
