[Serusers] diagram for NAT users

[Gustavo Villegas]

Dear Users
 I was wondering how is the diagram for NAT users, maybe this

NO NAT ENV


 UA----INVITE-------> SER----------INVITE---------->TERMINATION
 UA<----ACK-------> SER<----------ACK----------TERMINATION
 UA<----------------------RTP TRAFF------------------> TERMINATION


NAT ENV WITH , NATHELPER


NAT-UA----INVITE-------> SER----------INVITE---------->TERMINATION
NAT-UA<----ACK-------> SER<----------ACK----------TERMINATION
NAT-UA<-----RTP TRAFF<------>SER WITH NATHELPER<---------RTP
TRAFF----------------> TERMINATION
so the trafic in a nat environment is
nat-ua to ser , ser to termination, and viceversa termination to ser, ser to
nat-ua


any help will be thanks.
