Hi bin
u can actually go through this line from 3261. u can also grep
for the definitions of each tag in the below description
A dialog contains certain pieces of state needed for further message
transmissions within the dialog. This state consists of the dialog
ID, a local sequence number (used to order requests from the UA to
its peer), a remote sequence number (used to order requests from its
peer to the UA), a local URI, a remote URI, remote target, a boolean
flag called "secure", and a route set, which is an ordered list of
URIs. The route set is the list of servers that need to be traversed
to send a request to the peer. A dialog can also be in the "early"
state, which occurs when it is created with a provisional response,
and then transition to the "confirmed" state when a 2xx final
response arrives. For other responses, or if no response arrives at
all on that dialog, the early dialog terminates.
Thanks & Regards

[Sip-implementors] Dialog state machine
Hi,
In RFC3261, I found four state machines from transaction, but I can't find
any state machine picture about dialog, and the dialog information are
spread over a lot of RFCs, and I find a unique information about dialog
processing?
Thanks.
ABAI
