Hmm.. I wonder why the Cisco is sending an Info request? The only thing that
I think that might be causing this is the setting "isdn supp-service name
calling" which is supposed to map Q.931 calling-name attributes into a SIP
message. Since the Q.931 message comes a split-second after the initial call
setup on the PRI, the Cisco probably sends a second packet w/ the Calling
Name. All the Cisco documentation says about the feature is:

"isdn supp-service name calling

To set the calling name display parameters sent out an ISDN serial
interface, use the isdn supp-service name calling command in interface
configuration mode. To disable calling name delivery, use the no form of
this command."

Here is another call trace. This call path is similar, and I see the INFO
and the 403 Unauthorized again.
