UNCONFIRMED  errors and comments from readers: 


(11)  top;
The top of the drawing seems to be cropped off.

Also, it's not clear what the dashed line is indicating.

The first problem may be the cause of the second problem.


(31)  Under 3.;
vocall.3.0 should be vocal1.3.0


(49)  "Changing" section;
This whole section seems to be confused. It should suffice to ask this: why is he
setting "session transport udp" on a pots peer?


(67)  middle of page;
My guess is that:

   /user/java/...

should really be:

   /usr/java/...


{136} 1st paragraph under "Registration" section, 5th line;
I believe

", ... which could be a proxy server or the Redirect server itself."
should read
", ... which could be a proxy server or the Registrar server itself."
