I worked in/with network ops at a big US telco. Some of the engineers have ideas on which nodes have these intercepts (and what they are) based on the call flows they monitor and the level of access they have to troubleshoot problems further. I can’t guess the details further since that wasn’t my domain, but that part of opsec wasn’t fully hidden.

replyit's a (possibly virtual) appliance. It has connection to the intercept engine sitting somewhere in-band.
