Hi There,
I’m thinking of creating a free softphone app for mobile and desktop. What is your feature wish list for a softphone app in 2024?
Push notifications using FCM, to avoid battery drain and missed calls/messages. That would be huge.
Hi, sounds like a fun project. I’d suggest that a new app for use with Windows computers should at least as good as Microsip (meaning, it should have at least the same functionality, choice of settings, and flexibility - and as a bonus, it should also be as lean). That’s the standard I would aim to meet or surpass… 
This comment is from someone who cares about functionality, not appearance (skins, etc.), others will have other criteria, so as usual, YMWV. 
easier/faster configurations.
For a free softphone app in 2024, one of the key features to consider is seamless integration with various platforms and services. Many users today prefer something that allows them to easily handle both personal and business communications from one place without the hassle of switching between apps or accounts.
If you’re considering a wide range of communication needs, offering a SIP Dialer within the app would really help. This can simplify the process for users who want to make VoIP calls directly from the app, without needing additional software or workarounds.
