To setup your phones you have to access them from a computer using Internet Explorer or any other compatible browser as follows:
On the phones (9133i and 9112i models) use the arrow buttons to navigate to the“Network” menu and then select IP address.
While scrolling, you should find an ip address similar to 192.168.2.10.
Put this ip in your internet browser and you will see a popup screen asking for a user name and a password.
Enter “admin” as the user name and “22222” as the password. Then press OK.
On the next screen you should navigate to the menu option:
Advanced Settings -> Configuration server
Input the settings seen in the above image:
Download Protocol => HTTP
HTTP Server => voip1.voicemailtel.com
HTTP Path => phones
After that, click on “Save Settings” and restart the phone:
Reset => Restart phone
