    I guess I'll stay on TGY because it seems better than CHC for my purposes. Thanks for explaining so well!

    Alright, thanks for explaining! I think that it is too much hassle with even more disadvantages to move to CHC from TGY.

    Can anyone with experience help me with native call recording in TGY firmware. Is it viable to move to CHC for call recording and while doing so will my data remain as it is or will I have to backup and clean install?
