Google Pixel 4A 3CX App Request Failed Intermittently

[TaylorStevens23]

I have one user who is having intermittent issues with the 3CX smartphone application. He has a Google Pixel 4A. He is able to answer some call on his phone without issue. Other calls will ring but when he answers the app will not open or he receives a request failed alert. I am not able to identify any specific pattern to what calls he can and cannot take except all internal calls he is able to answer. The issue only comes from calls that come from outside 3CX but not all external calls have the same issue.

Here is the failed cause from the activity log:

failed, cause: Cause: 486 Busy Here/INVITE from 127.0.0.1:5080

Has anyone run into this type of issue with the 3CX app before?

3CX version? Android Version? App Version? Carrier? Have they rebooted their phone?

Sorry should have included that information in the question.

- 3CX Version: 16.0.655
- Android Version: Android 11
- App Version: 16.5.2
- Carrier: Google Fi
- Reboot: Yes

What kind of call volume? I have a very similar setup (Anroid 11, Google Fi carrier, but Pixel 3A XL phone) but I don't use that app a lot but it's always worked when I do.

This user is in our Help Desk queue so they get anywhere from 15-25 calls a day. The "Request Failed" error occurs intermittently on both Queue and Non-Queue calls.
