Read it here somewhere before but cant find it now but it related to the earpiece volume on the hub phone.

i'm not old nor deaf and the earpiece volume when turned up to max could do with a couple more notches upwards, compaired to the dect phone i had using plugged into the hub and my normal landline its really quieter ?

and fixes for dialling into the hub and upping the earpiece volume ? its so quiet that any background noise makes it difficult to hear.

regards
