Phones have and send IMEIs. These include a TAC [1] mapping directly to a phone model. The obvious solution would be to track false (accidental/misdial) calls, and if a phone model exceeds some metric (e.g. 5x the median), start fining/charging the manufacturer.
This would quickly cut down on these issues and if not, could at least provide funding to staff it.
Well, if the majority of accidental calls originate from the top n (n>0) manufactures it would be the most effective to address them. That's kinda how regulation works in many cases, see, e.g., privacy and safety enforcement in general.
