The link looks exactly the same as the last thread i posted but it has a different number. Got it at the same place as well. Enjoy!
UK: 0800-086-9897
Vouch, I got the same pop-up looking for keywords. Too bad the number is dead 
and I setup a windows 10 vm for it.
Any US Number?
@Chop#14177 Dead already? It worked for me just after i put the thread up.
EDIT: I just tried again, still seems up for me. Make sure your calling UK +0 and not US/CAN +1
@PepsiMan#14178 Just use FireRTC and call British numbers
@FOXYCallum1#14180 calling to uk via firertc is currently unavailable.
