I pretty sure I don't want to power cycle the router since if I do, the router will REALLY be stupid and I'll be hosed! I was able to delete the router's flash and but wasn't able to transfer the new flash to the router.

The router can see my PC and the router is basically naked. is a free program available on the Internet.SCW_RTR#$12/ flash:ĭestination filename ? You may have to install a protocol sniffing program to see what is happening on the lan. If you can’t see any activity in this window make sure there is not any firewall software running on your machine. On the LCD display of the phone you should see searching tftp and in the green window below you will see it accessing the file while it downloads and at the end if everything is working properly you should see this in the window.Īt this point the phone should be running the latest firmware and will have to be completely re-configured for its parameters. Once all the information is entered hit the OK or check button on the phone.Īt this point the phone should send out a tftp read request for the snomxxx.bin file. The tftp server is the IP address of the machine running pumpkin. Also, if you don't see the tftp server get the request, start over and leave the default gateway as 0.0.0.0. The subnet mask is usually 255.255.255.0 and default gateway would be 192.168.0.1 but do an ipconfig from your machine to be sure. Hit next and it will ask for the subnet mask, default, gateway and tftp server address. If you are on a private network just put in an available IP address on the private lan that is accessible by the tftp servers computer. Once the network is set up properly then power cycle or press reboot from the phones menu and hit any key immediately.Īt this point the phones LCD display will ask for the IP address for the phone. If you are network savvy then get a crossover cable and plug the phone directly into your computer. Tftp does not work well over the Internet since it does not use a reliable protocol so like TCP.

Before doing this make sure the snom phone is powered on and connected to the same hub as the PC for simplicity.
