Thank you very much for that info! Is this work for INVITE only (like in 
Asterisk) or is it possible to add headers to the other messages and 
especially to the replies?
BTW: Is there a way to send custom reply based on my decision (480 
contra 404, 502 contra 404 etc.)?

I like to know, if I add "Path" header to REGISTERs on my loadbalancer, 
than if Freeswitch succesfuly registeres NATed user with its real IP 
address instead of address of loadbalancer. And if Freeswitch will send 
NAT keep-alive packets to the NATed user based on Path header too...

I know it, but its not drawback for me. I need only basic option to 
manipulate SIP messages and really appreciate that Freeswitch is B2BUA 
and not proxy.
And, like I red somewhere, with much more better SIP stack (Sofia) than 
Asterisk has. The main things I'm missing in Asterisk is lack of PRACK 
(100 REL), not ever sent replies like 181 and 182, never used/sent 
Diversion header and last, but not least missing support for 
removing/altering headers...


Thanks again, Brian, for your answers and notable help!
