The softphone software controls all packets. per best practices, it should be set to DSCP EF.

Thanks for quick responds!

Per my understanding, softphone manages it. But can not find the option to set IP prec in the configuration manual. So is DSCP EF or IP prec 5 is set up by default for voice packets?

I think for the cisco products, yes.

Other software can do differently.
