I'll give this a try and let you know.

Could be, but I am unsure if this would be a SER limitation or SIP
limitation.

The packet trace reveals that the SPA3000 challenge is being swallowed
by SER. What I mean is, this 401 is not being sent back to UA1 so there
is nothing to see in this part of the leg. The 401 being sent back by
the SPA3000 looks as normal as a 401 being sent back by SER to a user
upon an INVITE. I can certainly grab these traces again tonight and
send them to you.
