4 stars: usability depends greatly on your phone. OnePlus 3 worked ok for chat, but would crash when answering calls about 90% of the time. on my pixel 2 it works pretty flawlessly Edit: recent versions of android automatically close apps overnight. Adding jabber to the exception list helps a lot.
3 stars: Goes in and out of signal on cloudy and rainy days. Have to have almost full bars for app to be clear. Appears to be worse on Fridays more than any other, which is typically a higher call volume day.
5 stars: Great communication application we can make clear conversation with our team, group etc, from any location in the world. It's make our work easier. Thank you
3 stars: I use this WFH and it's OK. Calling is fairly easy and VM is easy. There are times when it takes a long time to connect a call. An annoyance is the inability to end a call with a button like I can do from my native dialer. If another call comes in on my native phone, it often kicks my jabber off bluetooth.
3 stars: App performs well when running, however it constantly shuts itself off and I don't get calls since it isn't running. Not sure if this is my problem, but I do believe I have all necessary permissions set.
4 stars: Great app sometimes I answer a call and immediately diconects. Othe issue is pressing the disconnect button on my phone does not hang up the call.
5 stars: Been using this app for a while now...Guess what I love it. I haven't experienced any problems. Voice Call...
