Hello. 

What are the ways connect external users to the fs there? In such a scheme: 
 fs with real ip <-> internet <-> nat <-> sip-phone 


I read the topic http://wiki.freeswitch.org/wiki/External_profile # Switch_with_External_SoftPhone 

I did not understand several things: 
- That should be in exteranl5090.xml? Whole profile external.xml c changes in paragraphs 2,3? 
- Sofia/external5090 / <caller extension> @ xxxx: 5090 <- "What goes in xxxx? External UA IP? Domain?" I have the same question. that x.x.x.x should be? 

But this seems not quite what I need. Must be external to the subscriber is practically no different from internal.
