Trouble configuring Vitelity as a provider

[Tom Mazzotta]

I'm unable to get Askozia 1.0.3 to function with SIP service from Vitelity. I also have an account with DID4sale (inbound calls only) and it works fine, so I know that the rules on my firewall should be OK. I have already configured Vitelity to work directly w/ Asterisk 1.4 at another site with no problems as well. Using the "Asterisk via Registration" procedure documented on their support page, they suggest the following config:

Add the following to /etc/asterisk/sip.conf

At the top of your /etc/asterisk/sip.conf right after the general settings add:
register => my-username:my-password@inbound23.vitelity.net:5060

Near the bottom add:
[vitel-inbound]
type=friend
dtmfmode=auto
host=inbound23.vitelity.net
context=inbound
username=my-username
secret=my-password
allow=all
insecure=very
canreinvite=no

[vitel-outbound]
type=friend
dtmfmode=auto
host=outbound.vitelity.net
username=my-username
fromuser=my-username
trustrpid=yes
sendrpid=yes
secret=my-password
allow=all
canreinvite=no


I setup 2 providers, Vitel-IN and Vitel-OUT using the appropriate hostnames, and my username/password. The "Accounts: Providers" page shows neither a green nor red light to indicate registration. Any suggestions on what to try? Thanks!
