Receving error, failing to connect SIP device to Asterisk

I searched for this problem/error on here, but could not find it.

I am using a Linksys PAP2 device, which is basically a Sipura inside a Linksys box.

I used the guide and video from

revision3.com/systm/asterisk/

to set it up to my Astrisk server according their instructions:

extensions.conf

[quote][phone1]
exten => _X.,1,Answer
exten => _X.,2,Wait(2)
exten => _X.,3,Playback(tt-monkeys)
exten => _X.,4,Hangup[/quote]

SIP.conf

[quote][general]
context=default

; sipura1 describes the line that conects
; to the phone on our desk - the handset
[linksys]
type=friend
context=phone1
secret=password
host=192.168.1.7 ; IP of Linksys device
dtmfmode=rfc2833[/quote]

In the video they show how the Sipura SIP device is set up.
I copied the settings they showed, but instead I receive the following error message when I pick up the line (including fats busy signal after I try to dial).

Thanks for any assistance.

Okay I got it.

I was not properly stopping Asterisk and the updates I made to the .conf files where not taking place.

Thanks for the views.

FYI you do not need to restart asterisk. If you just make a change to sip.conf you can do this from the CLI: sip reload. If you make a change to extensions.conf you can do from the CLI: extensions reload. To reload all the configuration files at once simply type in the CLI: reload
