I found my main problem.  It was the way I was setting it up.  I was
putting the servers IP address in the authentication area.  This you
have to put asterisk instead.  And the IP address goes in the line area.

I  have upgraded to the 2.03o and I have both phones working just fine.
I had the choppy sound and found out it was a network cable that was
bad.  I have it working with great sound now on gsm which before it
would only work with alaw.  ulaw seems to still have some what I call
hickcups.  You hear it sound but every now and then you hear a skip.
