Chapter 2 Getting Started
Troubleshooting and Configuration FAQ
By default, the Admin account has no password. If a password is set for this account and you do not know what it is, you have to reset the device to its factory defaults. There are two options for resetting the device:
Option 877778 resets the unit to the configuration shipped from the ITSP and erases any configuration completed locally by the user.
Option 73738 resets the unit to the configuration shipped by Linksys and erases local configuration any provisioning configured by the ITSP.
To reset the SPA9000 to the factory defaults, perform the following steps:
A.Connect an analog phone to the SPA9000 and access the IVR by pressing ****.
B.Press 877778# to reset the unit to the defaults as it shipped from the ITSP or press 73738# to reset the unit to the defaults as it shipped from Linksys.
C.Press 1 to confirm the operation. Press * to cancel the operation.
D.Login to the unit using the Admin account without a password and reconfigure the unit.
13.My SPA9000 is behind a NAT device or firewall and I’m unable to make a call or I’m only receiving a
A.Configure your router to port forward “TCP port 80" to the ip address currently being used by SPA. If you do this often, we suggest that you use static IP address for the SPA, instead of DHCP. (For help with port forwarding, consult your router documentation)
B.On the Line tab of the administration web server, change the value of <Nat Mapping Enable> to yes. On the SIP tab; change <Substitute VIA Addr> to yes, and <EXT IP> to the IP address of your router.
C.Make sure you are not blocking the UDP PORT 5060,5061 and port for UDP packets in the range of
D.Adjust the NAT keepalive variables as follows:
E.Check the following settings on the administration web server:
F.Add a STUN server to allow traversal of UDP packets through the NAT device. On the SIP tab of the administration web server, set <STUN Enable> to yes, and enter the IP address of the STUN server in <STUN Server>.
STUN (Simple Traversal of UDP through NATs) is a protocol defined by RFC 3489, that allows a client behind a NAT device to find out its public address, the type of NAT it is behind, and the port associated on the Internet connection with a particular local port. This information is used to set up UDP communication between two hosts that are both behind NAT routers. Open source STUN software can be obtained at the following website:
Note STUN does not work with a symmetric NAT router. Enable debug through syslog (see FAQ#10), and set <STUN Test Enable> to yes. The messages indicate whether you have symmetric NAT or not.
14.I manually entered the proxy address into my SPA941 but it doesn't register with the SPA9000.
A.Make sure to have the SPA9000 IP address and the corresponding port, the default port is 6060 < Proxy Listen Port>. For example, enter 192.168.0.1:6060 in the Proxy location of the SPA941.
15.Why can’t I register the FXS ports to an outside proxy?
