12.0 Troubleshooting
12.1 Troubleshooting your Connection
If the Fonality Data Center is unable to establish a connection to your Fonality Phone System, you
may
need
to
adjust
your
firewall
configuration
to
allow
outbound
access
to
the
following
ports
from
the
Fonality
Phone
System
:
•
TCP/80
•
TCP/8000
•
TCP/9000
•
UDP/53
If you are unable to establish a connection to Fonality’s Data Center using the information above,
you should consider the following alternative configuration changes:
•
Create a rule allowing the IP address of the Fonality Phone System to make an outbound
connection to any host on any port.
•
It may be necessary to reboot the Fonality Phone System with CTRL+ALT+DEL from the
system console in order to reinitiate a new connection to the Fonality Data Center.
12.2 Getting Rid of Echo
If you hear an echo when using analog phone lines,
don’t worry
. This is
normal
when installing a
new phone system. You may need to calibrate the echo cancellation inside the Phone System to
eliminate echo. The following documents provide you with additional information to help start this
process:

You can contact our support group using the instructions in Section 11 if you need additional
assistance regarding echo.
IMPORTANT!
If you have a Watchguard firewall, or any firewall that examines
the data payload of TCP/IP packets, you may need to disable this functionality in your
firewall for traffic originating from the Fonality Phone System. Contact your firewall
vendor for details about how to accomplish this configuration.
