Getting the IP address

In order to configure the Cisco IP phone to be used along with our service, it is required to access it's web interface settings. For this, the IP address of the device must be acquired.

Status >> Network Status >> IPv4 Status

On this section, you'll need to take note of the IP address shown beside: " IP address ". It should read back something as: " 192.168.0.1 ".

Loggin into the Web interface

Once you have the IP address please open a web browser of your preference and it's URL bar enter the IP address you got by prepending: " http:// " and access it. If you selected Skip on the user/password prompt when you first plugged your IP phone, you will not be asked for either of them

When the page has loaded, on the top-right corner, click Admin Login, after that click advanced, the URL will look like: http://{IP}/admin/advanced

I.E: http://192.168.100.35/admin/advanced
