Yes, I upgraded to 3.1.22(LS) and the issue has dissapeared.

Anyway it scares me a little if some UAC don't allow certains parameters as:
  vsf=AAAAAAAAAB8AAAAAAAAAAAAAAAAAAAAAAEBvcGVuc2VyLmlsaW1pdC5lcw--

Maybe Linksys with old firmware didn't accepted that parameter because it's 
very long. Other parameters as "dialog" were allowed in Record-Route header.

Obviosly it's a bug in Linksys, but hope it doesn't occur in other common 
UACs.

Thank a lot ;)
