there are some cases when such behavior would be needed
I have strict port forwarding rules for some range of ports on my firewall.
they include rtp traffic allowed only to one machine.
consider scenario when user calls from outside of the local lan and is
behind nat.
invoking fix_nated_sdp would cause putting the proper ip address of
the natted client
invoking force_rtp_proxy afterwards would cause that this traffic
passing through
the given ipaddress (rtpproxy host)
this way all rtp traffic from outside local lan will go through rtpproxy host

maybe this can be done some other way?
