Hello,
I can help you to implement Audio conference call like in Swiggy, Ola,Uber any APP feature in your app. For implementing this feature, I would suggest you to use twilio 3rd party service, instead of building it from ground up ourselves with huge expense. There are few questions related to it as below:
que1) Have you build app for same?
Que2) Are you using any framework for backend, admin or mobile app?
Please start chat to discuss in detail and move ahead.
Looking forward to hearing from you for long-term honest and healthy business relations!
Thanks,
Gunjan
Right now, I am placing a placeholder bid as the business details are yet to be discussed.
