[OpenSIPS-Users] 408 Request Timeout with UDP

[SamyGo]

Im afraid thats not how this works, regarding your assumptions in last
paragraph.

The NAT related parameters get saved in location table as OpenSIPS sets
flags and upon a call to that user those are used immediately and no timer
is used as such.

Now at the time of signalling rtpproxy has no role to play to work NAT or
anything.  RTPproxy will just use IP addresses in SDP as instructed in the
script to have a media path.
