I have been able to use the following Cisco IP Phone with Asterisk.
- Cisco SPA303, Cisco SPA504, Cisco 7941 and Cisco 8941
The SPA version just work as they are real SIP clients, however the IP 
range, 7xxx, 8xxx, 9xxx are SCCP clients, converting them as you did to 
SIP clients, is the Cisco SIP client and runs over TCP, not UDP as a 
normal SIP client.
Coming back to your question, you will need to setup a DHCP with BOOTP 
and TFTP wit XML distribution, as you have done for the firmware 
distribution and Asterisk needs to have SIP wit TCP support.
Additionnaly you need to generate a Cisco SIP XML configuration file and 
place it on your TFTP server with the MAC address.
The directory and video I have never been able to get working, however 
as a SIP client, it works fine.
I have these phones running with a number of customers in production and 
they all work, we actually mix types of phones, as not to require 
customers to purchase new IP phones, however sometimes the effort and 
time, which translates into cost, is too high.

Better still use a Raspberry Pi as a IP Softphone, or your Android phone 
with SIP client.
