This is an interesting problem. I would venture to say that if you did NOT authenticate for those calls that you pass to a spa-3000, then that would work... that is, if your SERPROXY doesn't authenticate.
I'll give this a try and let you know.
is it possible that the problem is trying to authorize twice...once for your UAC<->SERPROXY and then the UAC<->SERPROXY<->UAS(SPA3000)
Could be, but I am unsure if this would be a SER limitation or SIP limitation.
Can you have multiple credentials in the same SIP packet? Seems like it should work...
Sorry, not much help I know. Do you have a packet trace?
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.
