The gateway receives an INVITE with a tag in the "To:" header, but can't find an existing dialog (=call-id + to-tag + from tag) to this INVITE. The gateway doen't treat the INVITE as the beginning of a new dialog, because the TO-tag is already present.
I think SIPPS should not use the to-tag recevied by ser in the second INVITE, as a 4xx respond does not create a dialog.

I keep getting the error: SIP/2.0 481 Call Leg/Transaction Does Not Exist.
No matter what the far end is. I am able to call this UA from anywhere After it registers. Anybody have any ideas?
Here is the an example call flow:

The only thing I notice that is weird is the 'Route' in the F4 packet.

Yes, Klaus is right. INVITE after digest challenge must not contain To tag, it is a completely different request -- there is not dialog yet.
