This is the only vpn ive used that allows my sip app to register while on the vpn. Put it on android tv box and it switched to ethernet,wifi,and streaming. Much faster than my regular vpn.Good linux and windows apps.Loved the fact that I can use the fastest dns of choice and it still shows my ip address is masked!Love that i can have 5 devices. Great app!Will likely ditch my vpn for this one.And easy on battery too.
