This
is the 200 OK (response to the INVITE) message as delivered to the
phone.
I
couldn't figure out what you were saying, so I went back to
the
ethereal trace. After the snom phone receives a 183
status
message, it sends a PRACK to the PROXY. This PRACK
is
OKed,
without a Record-route. The next message is an OK
responding to the original INVITE, which does indeed have a
Record-Route.
So,
you are saying that the OK to your PRACK needs a record
route?
I can
do that I think, because the OK to the INVITE does indeed
have
a
Record-route.
I
don't even know what a PRACK is for...
