disabled call monitor feature - how to enable?

[honk0504]

Hi @all,

I succeed in downgrading from T-GAP8DEUC_1024.1 -> T-GAP8DEUC_1015.1. THANK YOU VERY MUCH FOR THIS!!
I intend to do this because I want to use the messagebox, SMS, call monitor features of former firmwares. But actually I notice that messagebox,... work with 1015 neither. Can someone help me out with this?

Does nobody use this features (Text Message, SMS, call monitor, ...)?
Please, if you use this then tell me which firmware do you use. Thank you very much in advance.
