asterisk users - Jul 2003 - Problems getting 7960's to play nice with Asterisk

I'm trying to get my newly flashed 7960's to play nice with Asterisk,
but
I'm having some problems. I can get my 7960 to register with the proxy,
and if I dial my own extension, according to my dial plan asterisk should
transfer me to voice mail. Asterisk "thinks" its playing me voice mail
prompts, but the phone just rings busy. I'm using the 4.4 cisco flash.

Other things:
The phone constantly says "Ethernet Disconnected". Even though it
tftp's
configs and registers with the proxy.

I get no dialtone on the SIP phone.

I'm using the default diaplan.xml file.

I'm running asterisk from cvs as of yesterday. I have one zaptel interface
but I haven't configured * for it yet. (I figured being able to call
voicemail was a good first test).

Any help would be greatly appreciated!

here is my sip.cnf:
[general]

port = 5060           ; Port to bind to (SIP is 5060)
bindaddr = 192.168.3.5    ; Address to bind to (all addresses on machine)
allow=all             ; Allow all codecs
context = bogon-calls ; Send SIP callers that we don't know about here

[2000]

type=friend           ; This device takes and makes calls
username=2000         ; Username on device
secret=phone1         ; Password for device
host=dynamic          ; This host is not on the same IP addr every time
context=from-sip      ; Inbound calls from this host go here
mailbox=100           ; Activate the message waiting light if this
                      ; voicemailbox has messages in it
dtmfmode=rfc2833
;canreinvite=no

[2001]                ; Duplicate of 2000, except with different auth data

type=friend
username=2001
secret=2001test
host=dynamic
context=from-sip

Something is wrong with either the phone hardware itself, the network
port on the hub or switch it is attached to, the ethernet cable it is
connected with, or the 10/100 autonegotiation between the phone and the
switch. Any other problems you are having are quite likely due to these
network problems, and so you should fix this problem before you attempt
to debug any of the others.

The "Ethernet Disconnected" message on the phones is the equivalent of
having no link light on your NIC. Standard network connection debugging
applies.

Some tips: This problem is likely due to a bad cable or 10/100 auto
negotiation issues. Try known, working cables on a known working
switch/hub port to see if the problem occurs. Try plugging it into
another switch (preferably of different brand) if you have one. The 7960
cannot be forced to either 10 or 100mb operation, so if you do determine
that it's not the cable or phone hardware, you'll have to either find a
way to force 10 or 100mb operation on your switch or you'll have to get
a new one...

Once you get your phone hooked up to the network without problems, then
you can start looking at the software issues..
