Hi Francisco,

strange.. How frequent do you observe this? Did i understand you correctly, if 
this change in behaviour occur, it alter the Contact header in every 
forwarding? Do you get also some other problems, like a eventual crash, or 
errors in other areas? Do you use any custom (self written) module in your 
setup?

Cheers,

Henning
