1. I want queue calls bypassing DND, but if I'm not working and have DND on, I don't want people calling me directly and making my phone go off.Call quality even when it is working is really poor- nothing but complaints from people on the other end.

2. I don't need my phone ringing loudly every time a call comes in to my work number.

3. I set the ringtone to "custom" and chose "silent", but it appears to ignore this setting and loudly blasts the admittedly quite catchy 3CX built-in tune through the whole office every time a call comes in.

4. Because of the missing block feature, the app will often ring for calls that my desk phone does not allow through because they are blacklisted.Very buggy.

5. There are so very few things you can adjust with this app & I dislike the layout, the fact that my phone can't control the settings, and as of a few days ago I don't even get the whole screen to come up when a call cones in.

6. Calls drop constantly and it messes with my phone settings to where I don't get notifications for text messages or phone calls anymore.

7. I can't put my phone on silent though because I need to hear if someone calls my personal number.

8. I have my email notifications turned off but when I am on a call through 3cx and receive and email or text message, I get a series of loud beeps that last about 4 seconds in which the call is dead until the beeps are done.

9. When you're on a call, if another call comes through, 50% of the time, instead of another line ringing, it rings in your ear as if the app isn't open.

10. It rings at the same time your desk phone does and mobile access to the directory is convenient.

11. I get multiple instances of the same one incoming phone call, then the call drops completely.
