Help with Asterisk Voicemail & CME

Been searching for a few wks now on Integrating Asterisk Voicemail. I’ve found several helpful documents on the subject. I would like to utilize asterisk voicemail with my call manager express.
Here are the links I’ve been using to various degrees of success:

Has anyone successfully done this? I have posted another thread here, if someone would like to examine the configs.

The problem is that when I call an extension, it forwards it to the asterisk voicemail extension #, and I get a fast-busy.

I would like the voicemail to look like this:
105-Retrieve voicemail
106-Unavailable
107-Busy

My router config:
! This allows CME extensions to go to asterisk voicemail extensions:

dial-peer voice 101 voip
destination-pattern 10.
redirect ip2ip
session protocol sipv2
session target ipv4:192.168.1.77
dtmf-relay rtp-nte
codec g711alaw
no vad

! Config for extension
ephone-dn 11 dual-line
number 222
label 222
description test
