Hi,
All transactions should terminate first of all. And I think as dialog
is not confirmed so all OPTIONS method will be treated like out of dialog and
will be handled by UE B with some error response.
7 A sends ACK
8 B receives ACK.
Thanks and Regards,
Vivek Talwar

Subject: [Sip-implementors] Processing a 4xx, 5xx, 6xx response
Hi,
For a non-established dialogs how do we have a 400 Bad Request response ?
The scenario is as follows
1. A sends an INVITE to B
2. A gets 100 trying response
3. A sends lot many OPTIONS towards B
4. B does not respond to the OPTIONS
5. B responds with 400 Bad Request for the INVITE
6. A receives a 400 terminate indication
7. ???
What should happen at Step7? Do we terminate all the transactions (INVITE
and OPTIONS) and bring down the dialog?
If we terminate all the transactions and bring down the dialog, we will then
not receive a 408 Request Timeout response for the OPTIONS..
How should we handle a 4xx, 5xx , 6xx response for a non-established dialog?
