A non-Cisco logo can be displayed on the 7970 screen. Cisco’s documentation states the logo be a .PNG bitmap format.

Cisco 7970 cnf.xml file

A number of people have contacted me for assistance configuring the 7970 with Asterisk. The [MAC].conf.xml file is some what different from the 7940/60 series handsets. I have attached below an example config file which is working on my network. You will of course have to fill in all the server addresses and passwords.
BeBox Router & SIP
by jsaveker on Nov.26, 2010, under Asterisk
I have been experiencing many issues with my SIPGate and VOIPBuster trunks loosing the ability to accept inbound calls. The trunk would work for some time and then without warning incoming calls would not be routed to my Asterisk server. I would reboot my BeBox router when this happened and it would work again for a random amount of time.
This evening enough was enough and I began trawling through Google to ascertain what was going wrong. It appears the router has an inbuilt SIP portforwarding rule which interferes with my rules entered via the routers CLI.
The solution was to enter the following command at the BeBox CLI:
connection unbind application=SIP port=5060

If you have not already come across these things then head over to ebay. I picked one up BRAND NEW for £35. They support Vido Calls with Asterisk.
Cisco 7970 (SIP) with Asterisk 1.6
by jsaveker on Nov.20, 2010, under Asterisk, Cisco
I finally managed to get my Cisco 7970 series IP telephones working with my Asterisk 1.6 server. I settled with SIP70.8-3-1S which does appear to support XML push on my applications.
I will posting a complete walk through for the install, but until then feel free to see it in action:
