I have built custom corporate directories before using the Cisco IP Phone SDK. For those who don’t know, the IP Phone SDK contains a bunch of different ASP (Classic ASP) and JSP applications. (IIRC most of these apps were developed by Berbee. The same folks that put together the original InformaCast).
Anyway, building a new application using Classic ASP didn’t seem like a good idea. So, this time around, I built it from scratch using ASP.NET and C#. Right now the app is called the “NetCraftsmen Enterprise Directory” but we may change that.
Version 1.0 (actually, it is the third or fourth version but with a complete re-write) was built with the goal of providing the following key features:
Directory Lookup Rules
The ability to provide “Directory Lookup Rules” similar to what is found in CUCM. In a later release, I may even just absorb the Directory Lookup Rules from CUCM. For now, we provide a method via a local config. The main reason I went this route is to tie the lookup rules to different tenants on the system.
This was a feature from 1.0. Basically, we use the IP address to determine location and then apply dial rules based on the device’s location. This can come in handy when you have different abbreviated or off net dialing rules.
In a future release, I plan on adding some features from a previous version. Specifically, the ability to have different dialing rules for intra-cluster (i.e. inter-site) dialing rules. Perhaps adding in “filters” to allow some segmentation based on “who” is calling “whom”.
In previous “versions”, I used code which leveraged LDAP. This method was essentially based on the LDAP COM+ component Cisco provides in the SDK. I also had a separate “train” (if you will) that leveraged AXL/SOAP from CUCM.
In the new app, we added a few things. First, we have built in a way to have more than one directory and each directory can have more than one source. In the “dot zero” release, the sources can be a local directory cache and a CUCM cluster (via AXL/SOAP). The app blends the two sources into one. In the future, I expect to re-add an LDAP capability (rewritten, of course). I also plan to expand the app to allow for more than one CUCM cluster.
There are some other little bells and whistles, but nothing mind blowing (or even all that interesting?). I am thinking I may put in a few other features and possibly approach my fellow NetCraftsmen to see if we should package this app up for general availability. Of course, it wouldn’t be the first of its kind but I think we can add some interesting features that differentiate our offering.
If you think this would be something of interest, let me know.
