Calls just fail

Unable to make calls, it starts dialing and then fails with no notice.

Has serious potential, needs work.

Basic user would have a difficult time setting this up. Luckily I figured it out fairly easily but noticed the call push ringing future when you have multiple devices configured does not work properly. I have three devices configured where only the desktop would ring when I called the number. I hope they install call kit into this app so it performs like the regular calling app.

Also please for the love of humanity, give user is the option to change ringtones.

Definitely has a lot of promise in the sip app space.

Works great… until

It all works amazing, but then, when I give it access to my contacts, it takes a while and then it crashes. After that, there is no recovery except to uninstall, install back again and log in (without giving it access to contacts).

Have done it twice already. Same result.
