So many bugs

The quality of voice is perfect but there are major bugs in this app;
1- you can’t disconnect the call and the other party should hang up.
2- when you call someone, the other party sees weird numbers instead of your assigned number
3- most of the time you don’t have access to the call pad and don’t know who is calling. Moreover, you can’t answer the call. You hear the ring but since there is no pad to answer, you just can’t answer. It’s ridiculous. I just rate it as lowest phone app! Sorry

Greatest voip app available

I have used many voip apps over the years including Bria which is one of the best, but the sound quality of Mizu is better than all of them, even without the use of codec G729.
The strength of it, is its ability to automatically adjust itself to the your network conditions and phone capabilities.
The only complaint I have is the fact that the iPone version has much less settings than the Andriod version and there is no obvious way to purchase the Pro version.

Doesn’t work

Doesn’t work: doesn’t connect to server, doesn’t have options for manual connect: port, protocol. Not same as at screenshots at website.
