@MrT10001 Thank You for responding. I would like to check the link you provided. But I'm not using zenfone as primary device so sim's volte support don't matter much but for demonstration, it would very great. And as this port is older, I thought that maintainer might have discontinued support.

@x.Dub Thank you for responding. I am not using x00TD as primary phone and mostly use for experimentation. But if everything will probably work fine like sims and other features increase, I can make Asus zenfone m1 as my primary device.

Is Asus x00TD maintained anymore on Ubuntu Touch? I am not getting any updates ocer stable release. And please can you add volte call support?
