The app has potential, but it has some issues that need fixing. Currently, not all profiles work as intended—only the 'Meeting' profile functions properly. When I try to activate the 'Busy' profile, callers still hear the 'Meeting' profile instead. It would be great if the app could resolve this bug so that all profiles work as advertised. Looking forward to future updates!

When I try to create a Custom Profile, after completing the recording and pressing the Create Profile button, the application asks whether it is time-based or not. After selecting the option, it holds for processing and then displays the following error message: “Connection Error! Enable Mobile Data to use Call Manager.” I have already checked that mobile data is enabled and working properly, yet the error continues to appear every time I try to create a profile.

The app is not working for porting number, I have ported from Vodafone to Airtel. It's saying that, you can register and use the call manager for Airtel numbers only. Please fix the bug. Thanks. At present I have Airtel number....eventhough i am unable to access this app....even after request to the customer care support (they couldn't responded even after 3 days). Waste of time and money.
