Route sets need to be fastidiously and scrupulously conserved by both UAs on both sides in all in-dialog requests.

Hi Henning,
Yes I do have that enabled. What is happening is that one of the providers on IOS is sending a double record route on the INVITE, but it is getting lost somewhere so when I send a 'BYE', I get a "404 not here". When I look at the SIP message I see only one of the record routes from the INVITE, therefore my assumption is, this is what is causing the 404, because everything else looks good.
