Bug description

For quite some time, intermittently voice or video calls will come in but not ring at all. This morning I made a date with someone to talk over Signal at a particular time. I waited and waited, but after 5min after our planned meeting time, I went to dial them. And that's when I saw the red 'Missed video call'. This happens fairly frequently.

Steps to reproduce

• I cannot reliably reproduce it, as it happens randomly (or perhaps only for certain callers). I have not been able to discern a pattern.
• If I ask my wife to call right after as a test, it will ring.

Actual result: No ring. Nothing in Android notification list. just a 'Missed video call' message in red in the relevant conversation Expected result: Phone should ring and present the ACCEPT/DECLINE pop-up prompt.

Hi there, thanks for the report. I chatted with our calling team and the last call in your logs shows that you were slow to receive messages from the caller needed to establish the call connection between the two of you. Would you be able to get the logs from the caller?

This issue is very common and this happens to all the users mostly

Would you be able to provide debuglogs to help us figure out what's going wrong for you?
