What happens to the ENDC bearer during VoLTE call?

Hello Experts.

What happens to the ENDC bearer during VoLTE call?

It depends on settings. Can be kept or released.

This is how it is with Huawei.

I mean, SCG released but QCI9 bearer kept of course.

Can this be suspended?

As far as I know, it is better not to split Volte bearers in the ENDC mode.
