If the modified RTP and non-modified RTP modules are on the same machine and most regular calls are already making use of the RTP, then the IP's shouldn't change at all. So the parties involved in the tapping will still see the same IP address at the providers end, which shouldn't give it away if they are being tapped.
most of calls do use RTP but that can't be said about RTP relay. RTP relay is not used that frequently (at least in well engineered setups), which is good. Constant use of RTP relay is a poor setup having bad impact on QoS and scalability.
It would be nice to ignore,
I suggest reading before replying would better facilitate the technical discussion here. I actually didn't suggest to ignore LI. I suggested ignoring the possibility of advanced caller to learn that a call is not routed peer-to-peer. Other alternatives may be that expensive or hard-to-build that they do not appear entirely practicable.
