Can I connect two devices at once?

I currently have my ATA set up with FPL.

I want to input the SIP settings in my Android Phone Dialer, but it's not connecting when I make the call (it shows Internet Calling when I dial).

I unplugged my ATA and tried again with my Android Phone but still no go.

You can only connect with one device at a time to make things work properly.

You can connect 2, but they will keep stealing registration from each other and you won't really know which will ring, if any.

Your Phone Dialer should work, just make double sure you are entering the password right and the username includes the initial 1.
