I'm still working on debugging communication between
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.
