We're currently creating what will hopefully be a useful technical resource for all those Unified Comms engineers out there, plus those studying for CCNA Voice.
We've uploaded various vanilla configs for configuring voice gateways, LAN switches etc. Plus there are network diagrams, videos and links for further cisco configuration and design guides.
Also Excellent section displaying recent Cisco Netpro posts and also the Hottest Cisco TAC Unified Comms Issues. Give it a go and let me know your thoughts.
