1. Note2: The softphone service might try to run in the background and request to ignore battery optimizations only if push notifications are impossible in your network, for example if your SIP server is on private IP and doesn't support push notifications. -The VoIP phone can be used with any VoIP service provider, any softswitch or PBX, including Asterisk, voipswitch, 3CX, Cisco, FreePBX, Elastix, OpenSIPS and others. -Works on any network above 12 kbits (3G, 4G, LTE, 5G, WiFi, others). -Free for non-commercial usage. No advertisements. -Minimal CPU and battery usage.

1. 3.5 stars.It worked great a couple years ago, but recent changes have made it unusable for me I used MizuDroid for testing phone systems I manage, so I need multiple accounts.
2. Since it's free I'm giving it 5 stars but the devs should maybe look at an issue, where if your screen locks or you leave the app while on call for to long the other person on the call can no longer hear you, until you return to the appamazing sip client but call audio often breaks up even over wifi.
3. However the reason for this 3 star review instead of 5 is that while not connected to any sip server (the only sip server configured being a private one) I have received a call from spam bot.
4. I guess it is acceptable to replace in app adds with in app spam but this is deceptive to users who expected this app to be real deal (free+no adds) and should have been specified in description.App works great.
5. It has improved if the sip server is at the location continent of the received call, NOT the location of the call maker.Probably the best SIP/VOIP app.
6. Edit: still not detecting hangup, stuck, pressing red hangup does nothing, have to kill tasks to get it going again.
7. Still, the app is easy to setup and configure, intuitive design, compatable with various providers, very customizable, and loaded with features.
8. Also, the app nagging me to enable foreground service for incoming calls-- when I do not use it for normal calling-- every time I try to use the app ticks me off.Full-featured SIP client.
9. Mizu fails to detect call was hung up.
10. I wish I had left well enough alone with the previous version.Great app that does what it claims to do.
11. I would love to see all this fixed, because all the alternatives I find more frustrating to work with and have their share of problems.
