Hi Vic,

It seems your provider is truncating your RR header....and there is no 
much you can do about that (except changing it :) ).

As I see you do FROM and TO changing and dialog support, I suggest to 
upgrade to 1.8 where the TO and FROM changing is done based on dialog 
and not RR hdr, so your header eill not have the vsf and vst params -> 
much shorter.
