Issu: Incoming Call Screen appears without Ringtone

[ashudevcodes]

Hey, this video call application is really great. I am using this application to communicate with my friends in a private way, and it's really good. I had a great experience using it. However, I noticed that when I receive an incoming call, the incoming call screen appears, but there is no ringtone playing when my friend is calling. I have already implemented a fix for this issue by adding a ringtone feature that plays when an incoming call is received. If you agree, I will make a PR with the changes. You can then review the PR to see if it meets the requirements and is up to the project's standards. So, can I make a PR?
