Speaking of Twinkle, that is the UA I was referring to in my previous post on 
this thread. During a re-INVITE it does not return an Record-Route list with 
its 200 OK. This does not violate the spec but it causes inter-working 
problems with asterisk because asterisk appears to create an empty route set 
and the ACK will not find its way. I had a brief Email exchange with the 
author of Twinkle. He was reluctant to implement a work around to fix a 
problem with another UA. Other UA's that I have encountered send an RR list 
with the 200 OK during re-INVITE.
