Cons
Con No easy End-to-End Encryption setup
Con Features not available out of the box
Difficult to setup the many features it offers. The easy docker installation is for the application only, not it's feature sets. Requires a license for full-set of features.
Con Centralized
Con Poorly made iOS app
Built natively using React it suffers from unresponsiveness, input lag, and sometimes broken services. Coupled with a bad user experience.
Con Poorly made Android app
The Android application is just a badly wrapped web-view which does not perform well and has no form of offline caching whatsoever.
Con Self-Hosted
This doesn't work for every type of company. Mainly great for those concerned with privacy, security, compliance and control of your data/information.
Con UI not very intuitive
Implementation of Contacts and missing calls are not very intuitive.
Splitted View (left Contacts, right Call-History) would be much better as current look&feel.
UI don't mind the "less clicks are better" philosophy. It looks a bit thrown together. Some Icons here, some there.. no navigation strategy are used (like known from webpages)
Con Limited to flatpack installs
Yet another container service to keep up with.
Con Doesn't ring on incoming calls
Even if the Audio-File exists and can be played in the Settings-Dialog, it doesn't ring for an incoming call. Worked some time ago, currently not.
Con No Plugins available to add external Address-Books for contacts
would be nice to be able to add NextCloud, GoogleContacts or other Cloud-Services, or just an local Address-Book (like Thunderbird)
Con Up-to-date version in 2020 can only be compiled from source
There is either an outdated version in Ubuntu repos, official flatpak install has been broken for over 6 months, so you're left with compiling from source.
