Neel,

Thanks for the reply.  I don't have ethereal on the machine and not sure how 
to capture - non-graphic terminal environment.  Below is output from 
tcpdump.  In this session, I see two "202 Accepted" from 1.4.0, only one 
"don't know" notice.  Interestingly, identical tests between two 1.2.13 
Asterisk does not produce this.

I assume that this is nothing serious, because the session completes without 
any problem, and the message is only a notice.  If anything, I'll simply 
revert to 1.2. (These are non-production.)
