I've been watching reruns of Stargate SG-1 on Netflix as of late and I have to laugh when I see some of their props. Clearly they had a telecom guy as one of their prop managers - so far I've seen a Mitel SX200 console being used and a Nortel Option 61/81 cabinet that was retrofitted with LEDs to make it look "scientific".
