You will need to host your application on a separate web server. There is no way to modify the default corporate directory application on the CUCM appliance. I had to recently do this exact thing for a customer. What I did was take the the multi-directory application from the IP Phone SDK (http://developer.cisco.com/) and tweak it heavily to incorporate an AXL/SOAP query function. I stuck with .ASP because it was easy and about 50-60% of the code I needed was already in the SDK example (and the example is in ASP). I replaced the LDAP functions with a AXL/SOAP function. The IIS server hosting the ASP makes the query to CUCM and presents the results. I haven't had an issue with that process yet. However, I just finished this app and the customer has not started testing.
You will need to be aware of a noticeable change in how 7.1 handles corporate directory versus all previous versions. I touch on this in my blog here: http://www.netcraftsmen.net/component/content/article/70-unified-communications/714-how-to-disable-corporate-directory-in-cucm-7x.html
It will matter to you when you want to host your own corp directory application. You will also need to remember that if your users are using other directories, your script will need to present them all to the phone. You will see what I mean when you point a phone to your custom directory. Test first, of course.
As far as doing the AXL/SOAP query. If you don't know where to start then you need to read up on the AXL/SOAP interface and developers API. This is located at http://developer.cisco.com/. If you have a valid CCO account then you should be able to access this portal. Here's the cliff notes:
1. The table you are interested in is enduser
2. The fields you are interested in are: firstname, lastname, telephonenumber, department
3. If you want to play with looking at SOAP/XML messages that you need to deal with when playing in the sandbox with AXL, check out the AXL SQL Query toolkit. I did a little series on it here:
http://www.netcraftsmen.net/component/content/article/70-unified-communications/715-running-sql-queries-on-cucm-6x7x-using-axl-soap-toolkit-part-1.html
Actually, there is source code provided by Cisco with the toolkit the blog series focuses on. It is in Java, so not directly portable to ASP. Even if you are using MS javascript.
So, bottom line is that you have to build an ASP for yourself and add in the AXL/SOAP query capabilities. How difficult this is depends on how comfy you are with the whole prospect.
HTH.
