Hi All,

	In document at the below link

http://www.ietf.org/internet-drafts/draft-ietf-sipping-basic-call-flows-01.t
xt
section 3.6 "Session via Redirect and Proxy Servers with the SDP in ACK".

I am wondering if someone can explain to me how the INVITE (F4) is directed
from User A to Proxy 3 without any Route header being included in the
message.

I have been trying to figure this out for a while and I'd really appreciate
any feedback asap

Thanks in advance,
Val
