Hi there.  I'm a noobie to Kamailio and Freeswitch... but I'm trying to follow the article located here: 

http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc

I've tried to add all the sections marked with WITH_FREESWITCH in the sample config in the article into my own kamailio-advanced.cfg file. 
Here's what my cfg file looks like:

I've restarted kamailio after making these changes. 
Then I tried to dial 41 to listen to vmail or 44999 to leave a message for user 999 but both return a busy tone. 

Any suggestions would be appreciated.
Thanks.
