Any idea how to set up a cisco 7902 phone using SCCP? I can ping the phone through the network and I can view al its setting using a web browser but I can’t get a dialtone.
When I view the phone’s TftpServer, it is noted down as 0.0.0.0. How do i change the 7902’s TFT server so i know it will at least that my 7920 phone can communicate with my asterisk pbx? Thanks.
Check out Asterisk phone cisco 79xx.
This is not an asterisk issue. In your /etc/dhcpd.conf file, add the following line:
option tftp-server-name “ip.of.tftp.server”;
Make sure your TFTP server is running and all necessary ports are open on your firewall (you can check by using iptables -L )You can add this inside or outside of a subnet {}, it doesn’t matter. The 7902s are pretty much plug and play if you can get them talking to the tftp server.
