[Asterisk-Users] registration failure

[Roger]

I feel I'm on the verge of setting up a pbx for handling internal calls 
only...

The last problem - I think - I've run into is w/ the phone registration

running

asterisk -vvvc

I get a bunch of messages looking like so

Apr  6 14:46:05 NOTICE[1116957488]: chan_sip.c:5623 handle_request: 
Registration from 'sip:2001 at 192.168.22.254' failed for '192.168.22.1'

Registration from 'sip:2000 at 192.168.22.254' failed for '192.168.22.1'

The ips in the 22.1 and 22.2 are 2 Cisco 7940 phones running SIP image 
6.3. The host 22.254 is the dhcp/tftp server/asterisk box

When I attempt to dial extension 2000 from ext 2001 I get the following...

And from the SIP<mac>.cnf

I have

####### New Parameters added in Release 3.0 ######

# Phone Prompt (The prompt that will be displayed on console and telnet)
phone_prompt:   "SIP Phone"      ; Limited to 15 characters (Default - 
SIP Phone)

# Phone Password (Password to be used for console or telnet login)
phone_password: "cisco" ; Limited to 31 characters (Default - cisco)

# User classifcation used when Registering [ none(default), phone, ip ]
user_info: 2001

I really really I'm close - just stuck on this last problem. 

Any suggestions would be appreciated.
