Hi,
Did you make the Cisco 78xx work ?
Do you mind to share the SEPxxxx.cnf.xml file or do you used another way!
As far I am aware, the Cisco phones uses an external app as phonebook and call history, there are no this information inside the phones. You can use usecallmanager.nz to learn more about configuration. As far I remember, there are linux daemon for contacts.
