Problematic

Ive been using this app for receiving calls from my work/business number to my phone for about 6 months now. First issue is that it must be open to receive calls. There is no option to automatically receive call notifications without opening th app ans having it run in the background.

The second issue is that the call history is sporadic, where some calls that should be patched through are, and some are not.

The third issue is that there is no text functionality and a lot of business is conducted by text which forces me to use my regular cell number and defeats the purpose of having one business number for both office and cellphone.

Powerful and easy to use

This app is powerful and easy to use, the meeting setup is easy, I can use it to audio/video call, host meeting with internal and external attendees, message chat, OA process, AI helper, etc. And the desktop version even supports more features. I love this app so much that it supports my daily work very well!

Login broken

This app used to be fantastic but unfortunately recent updates seem to have broken login and it is now unusable

Mute!!

Need a setting on iPhone app to silence/mute calls for after hours. Android version seems to have a way to do that.
