It doesn't. The signaling IP is just a hint from where to expect media for 
that phone, so the caller/called will be correctly identified when they 
sign in and not be confused with eachother. But it's not vital, it's just 
a helper and things should work even if it's not set correctly.

If this doesn't work in that scenario, I think a better solution is to 
improve the sign-in mechanism, than to complicate the mediaproxy setup 
process with extra avps. One of the reasons behind mediaproxy's design is 
to move the complex setup logic in the background (in mediaproxy itself) 
instead of requiring the user to pass many arguments/avps to control the 
behavior.
