Greg,
you are right, that is a ser bug -- we experienced and fixed it at
our iptel.org site but have not released a patch. Feel free to download
source code for the auth module in use at iptel
http://www.iptel.org/~jiri/ser/auth.tar.gz
That should hopefuly help. If you problem persists, let us know.

I'm still working on debugging communication

my SER server and nikotel's. One of the engineers there
did a very thorough disection of the INVITE packet.
I notice a '5' sneaking in...it must be introduced by the
SER server.
Here is the packet:

If I was guessing, I'd say that the 'consume credentials' was leaving
the last two characters
of the Authorization line. That is, the 5 and the \r (somehow the \n
is removed).
I'm running version 0.8.10.
