This is not entirely true; you still need to have a logo if you want to federate with Microsoft and it still works.
But I haven’t found out how to do it in any of the OCS 2007 documentation; however it still works if you do it the old LCS 2005 way.
First, download and install LCS 2005 Res Kit

Creating and deploying icons
-------------------------------
Before the Branding application can be deployed, the icon itself must be
created and deployed. If the icon is to be displayed in Microsoft Office
Communicator 2005, the icon must conform to the following rules-
- File format is .png.
- File size does not exceed 8 KB.
- Icon dimensions must be 16 x 16 pixels.
- Maximum 32 bits per pixel.
This program supports deployment of two icons for federated traffic,
one for presence documents leaving the network and one for presence documents
entering the network. The external icon is the one displayed to external
users on behalf of local users. Both icons must be deployed on an external facing
Web server that allows browsers to display the image from inside and outside
the local domain by using the URLs specified in the BrandingUrl and
IncomingDefaultFederationBrandingUrl variables, respectively. Only HTTPS
(secure HTTP) URLs will work with all supported clients.
Configuration and Setup
-----------------------
To install and run this sample, you will need the following software:
- Microsoft® Windows Server™ 2003

1. First, open the Branding.am script and change the BrandingUrl property [MC2]to contain
the appropriate branding image for your deployment.

Server 2005.
