[OpenSIPS-Users] OpenSIPS 1.7.0 Topology Hiding and NAT Traversal

[Jeremy Childs]

I'm having a problem with the dialog module's topology hiding when a UA 
is behind a NAT.

If I call

if (nat_uac_test()) {
     fix_nated_contact();
}
topology_hiding();

The Contact header is rewritten twice - once by fix_nated_contact() and 
again by topology_hiding(). This results in an invalid contact header.

Is there an obvious way I'm missing that could make these two modules 
coexist, or is the best solution to add NAT knowledge to 
dlg_tophiding.c? This seems like a lot of code to duplicate.
