It is incorrect to say that a voice server can't know where the phone is. IPT systems that integrate with the network can provide MORE Emergency functionality than a TDM system. It can locate the phone based on the port the phone is connected to and then apply logic to handle the call beyond just contacting the local 911 office. If a system doesn't offer this level of integration with the network, look elsewhere.
Also, deploying analog phones in large numbers through a voice gateway rarely makes sense. It reduces the M/A/C savings that IPT brings. If you are going to leave large numbers of analog phones out there, just connect a voice gateway to your existing PBX and move on. But don't call that IPTelephony.

Reason #1001 why VoIP should be scaled to a minimal installation. Why would anybody install a potential security breach when many other, cheaper options exist?
