OK, but in the current case another question. Is nat_bflag appear in transaction when call goes TO uac behind nat (by using lookup(), for example), or it appears in transaction when call goes FROM uac behind nat?
Thank you.

Isn't that set?

In your opensips.cfg you call "fix_nated_contact()" on both route and reply route. that's why it changes the route. There is no such a thing as direction in opensips unless it's implemented in your logic. A message goes through your route or reply route scripts when it reaches opensips.

There is such scheme UAC1 (softphone behind nat) à Opensips -> UAC2 (another softswitch), i.e. UAC1 initiates a call to Opensips and a signaling port = 5068. So UAC2 becomes ringing by sending 183 message. In attachment 183 message from UAC2 and some parts of opensips.cfg After 183 processing by Opensips port in Contact header of 183 (and later 200 OK) messages become 5060, i.e. Opensips detects NAT and changes Contact header. So my question is, Why does Opensips changes Contact header? Once Opensips detects nat transaction (setting setflag(21)) is it check all reply messages (and doesn`t matter from which UAC they have been received) or Opensips can detect direction and makes decision about nat process?
