[Serusers] REGISTER loops from specific location

[Iqbal]

the iptel.org guys are clever :-)

Run a ngrep for both, and see what it returns, also iptel is probably 
fixing all your NAT stuff at there end, whereas you might have a config 
error, which is not fixing all the parameters, again just a guess
