When making a call that requires pressing a number when I press the number the "call fails"

Thanks for reaching out cowboyk,

It sounds like you're dropping calls when using the number pad inside the Phone app while on a call. We can help.

This is definitely unusual, and our recommendation would be to confirm that you are using a valid number when navigating the menu you hear on your call. If the issue persists, you can connect with Apple directly using either Get Support or if you're in a region without direct support options, you can also Contact Apple for support and service.

Hope that helps.
