Telephone Coding standard values?

[marcel151]

Hello,

I maybe messed up my telephone config. Problem is that Car Play is crashing when a call comes in or when I call someone via Car Play most of the time. I also have a SIM card inserted, which is a Multi-SIM of my phone. Maybe both phones interfere each other?

Here are 2 screenshots of my telephone config. Can somebody provide standard coding for telephone? SIM should just be for data when Car Play is used.
