Good to see you Abhinav! I am experienced in VoIP app development, Flutter, and push notification setup with Firebase Cloud Messaging (FCM). I have successfully completed similar projects involving firmware updates and integration of SIP calling functionalities.
For your project, I will update the VoIP app code to implement a call alert feature similar to WhatsApp calling alerts. This feature will handle both foreground and background states on both Android and iOS platforms. By leveraging my expertise in Flutter and push notification setup, I will ensure that the call alert functionality seamlessly integrates with the existing app architecture.
Please initiate the chat for further discussions and my previous work. Thank you.
