It requires a listening/recording/transmission device in or on the outside of the room.
I'm pretty sure a crafty spook-geek could transform your average desk phone into a handy-dandy surveillance "bug".
Re “It requires a listening/recording/transmission device in or on the outside of the room”.
Maybe I’ve been watching too many crime, war, and SciFi shows but I’ve heard that you can actually use an existing electrical wiring system to eavesdrop by internally turning on a radio, phone, etc. That becomes the listening device and picks up sounds in the room which are then transmitted back along the electrical wiring to a machine that can record them.
Anybody ever heard of this technique or am I watching too many Mystery Theater 3000 shows?
Bugging telephone traffic doesn’t require physical bugs anymore. Cell phone numbers get cloned. Something similar can happen to land-lines at relays. There’s no evidence of a ‘bug’ for a Secret Service sweep to reveal.
Heck... Go to NEFLIX and rent HBO’s “The Wire”. The show gives you a primer on how it’s done. And I’m sure that the NSA spooks at Forts Mead & Huachuca have a few new wrinkles we haven’t even thought of.
Don’t forget that Newt’s phone calls were recorded by an old couple in florida using a off-the-shelf scanner back in the 90’s.
If the conversation you are interested in is only done PERSON TO PERSON in a room in Trump Tower, all the winks and nudges to AT&T won’t help at all.

It can be accomplished with a malicious program inserted into the buildings VoIP servers/switches to turn every phone into a listening device. possibly a simple reprogram , possibly through a replacement of a prom/eeprom chip.
