ČEZ IP Telephony Data Centers

2010

I designed the IP addressing and cabling and created documentation; I first simulated the network in GNS3. I designed and tested redundant interconnection of the data centers as well as interconnection of the video and radio networks with the IPT network.

I integrated Cisco ASA firewalls into the data centers, moved servers behind them, tuned the rules, and handled SCCP protocol inspection and voicemail registration with Cisco Unified Communications Manager. I brought the project through to acceptance testing.
