HI Thomas,

Why do you have a Requirement to send 401 after 202?
Why your Authentication takes more time?

Still, I dont think you can send 401 after 202.

rgds,
Prince

Immediately after sending the 202, the notifier must send a NOTIFY, but
it can use "Subscription-State: pending" to indicate that the
subscription has been fully approved by the notifier.  If the notifier
eventually decides to reject the subscription, it would send another
NOTIFY with "Subscription-State: terminated".

If you are using SIP authentication as a preliminary permission check,
you would apply that first, to the initial SUBSCRIBE.
