I have a USB DSL
modem.
DSL modems with only a USB interface are not supported.
I have a satellite
broadband Internet
connection.
Satellite broadband connections are not supported.
I can’t get this to
work with my
company’s Virtual
Private Network
(VPN).
AT&T CallVantage
®
Service supports most VPN clients.
Check the settings on your VPN Client to verify that “keepalive”
messages are disabled. Also, select “allow VPN to pass through
NAT”, if this option is available. You may have to disable (un-
check) “negotiate UDP encapsulation with VPN tunnel server”,
if this option is available. You should also contact your
network administrator to understand what other settings may
need to be modifi ed for your setup.
I cannot get AT&T
CallVantage
Service to work. I
need assistance.
For best results, download and run the AT&T CallVantage
Assistant. This is a downloadable self-extracting fi le that checks
your system confi guration, provides system information, walks
you through the TA installation, and performs basic diagnostics
and troubleshooting. If you are a new customer and this is the
fi rst time you are installing your TA, it will automatically walk you
through the TA activation process.
My data service is
lost every once in a
while, but I still have
a dial tone.
I am using a home
router and have to
reboot everything to
get the data to work
again.
If you are using a home router, make sure your device has the
most up-to-date software available from the manufacturer.
Software updates are readily available from the manufacturer’s
Web site. Check their site for your model, and compare the
most recent version they are offering against the version your
device is running. If they are not the same, follow the upgrade
instructions on the Web site or in your router’s manual.
I am having voice
quality problems
with my phone.
1. If you set up your TA behind your router (i.e. you followed
the installation steps in Appendix A), your data connection
may be interfering with your voice connection and reducing the
quality of your calls. To ensure the highest call quality
AT&T recommends that you follow the standard setup with the
TA in front of the router, as described in Steps 1-6 of this guide.
2. If your TA is in front of your router, check your cable/DSL
speed at http://www.broadbandreports.com/stest. Your cable/
DSL provider’s connection speed can vary; if your speed does
not meet the minimum requirements of 90 Kbps uplink and
downlink at this time, you may want to try again later.
3. You can also try disconnecting the phone and using a
different corded or cordless phone.
