Bug description

Description:
It is not possible to switch to a new phone number using call verification.

Steps to Reproduce:

1. Navigate to Settings.
2. Select Account.
3. Click on Change phone number.

The screen displays the following message:

"Use this to change your current phone number to a new phone number. You can't undo this change. Before continuing, make sure your new number can receive SMS or calls."

I am using a VoIP number that is capable of receiving calls.

Upon following the process, there is no option to switch to phone call verification. I attempted to enter a random verification code, but the process fails. There is no option for or fallback to call verification.

Expected Behavior:
The app should provide an option to use phone call verification instead of just SMS verification, or allow switching to phone call verification if SMS fails.

Actual Behavior:
Only SMS verification is offered, and there is no option to switch to phone call verification.

Environment:
VoIP number capable of receiving calls. Signal on Android
