DirectoryURL: Application i am using is based on mysql. More info 79XX XML applications http://www.voip-info.org/wiki/view/Asterisk+Cisco+79XX+XML+Services

In this example my asterisk server IP address is 192.168.0.1 and phones are leasing ip addresses from dhcp pool 192.168.0.0/24.
I tested it with 3 type of phone Cisco 7910, 7960 and 7940 with 7914 addon panel.
You must set a phone type to 7914 and give the 7940 SEP MAC address which is connected to the panel, in case you want to use a 7914 addon panel. And create as many speeddial lines.
