Unified Comm. TCP/UDP port usage and ACLs

Have you ever looked at an access list and wondered what the port numbers correspond to, other than the obvious ones that are well-known or documented in /etc/services?  I've been working on ACLs for classification and marking of voice/video control traffic and David Hailey of Netcraftsmen pointed me to a Cisco document that has a nice list of protocols/ports used in the Cisco Unified Communications products.

http://www.google.com/search?q=site%3Acisco.com+unified+communications+port+usage

 There are versions for different versions of Cisco's products.  Add "+6.0" or "+7.0" to specify the version you want.  For versions older than 6, you'll need to change the search, replacing "communications" with "callmanager", because the product name changed.  I found that the search string above worked pretty well without designating the version number.  It provided links to a number of different product versions.

Good luck with your ACLs!
