Worked fine in the begining.
Now local calls are not clear.One has to redail every minute or so to hear the other person
Internation calls are dropped after the phone is picked up.This costs money
Two weekends on the "live chat" promised a fix and a follow up email
Did not happen
Called "live chat" and they want to run me through the same again
Waste of time and money.
So it turns out a very expensive gadget in time and lost money
When it worked it was great, nothings changed on my side so they have lost the system, maybe they are getting to big and cannot cope
