Hi, I've got this information from my ISP for using with VOIP but I am not really sure where to configure it on the SPA3102:
Thanks in advance!
If you have your PC plugged into the yellow Ethernet port on the SPA3102, then you will need to access the device's interface by going to: http://192.168.0.1/admin/voice/advanced/
Once the GUI loads:
-Click on the "Line 1" tab.
-Scroll down until you see "Proxy and Registration" and "Subscriber Information"
That should do it.
