there is nothing like this. the closest thing to it is something called TTP (trusted third party), that works as intermediary between telco and law enforcement agencies. they perform wiretap order processing, setups actual wiretaps, collect/bundle and ship away to agencies wiretapped information. but there is a bunch of them and you (telco) don't have to use them
