Hi John,
I believe outbound-11 addresses this concern. The UA is now allowed
to request flow token handling on a REGISTER or any dialog-forming
request.
thanks,

In section 4.3 "Sending requests" it states:
"The UA performs normal DNS resolution on the next hop URI (as
described in RFC 3263 [4]) to find a protocol, IP address, and
port.
For protocols that don't use TLS, if the UA has an existing flow to
this IP address, and port with the correct protocol, then the UA
MUST
use the existing connection. For TLS protocols, there MUST also
be a
match between the host production in the next hop and one of the
URIs
contained in the subjectAltName in the peer certificate. If the UA
cannot use one of the existing flows, then it SHOULD form a new
flow
by sending a datagram or opening a new connection to the next
hop, as
appropriate for the transport protocol."
This seems to imply that the UA simply sends the request on a new
flow,
yet there are no proxy procedures defined for receiving a non-register
request on a new flow. So perhaps what is intended is that UA should
register again using the new flow, and then send the request on the
new
flow. Whatever the intention, it seems some clarification is required.
