This 4-day seminar contains theoretical as well as practical sections, that will present to the participants how analog voice networks, VoIP networks and Video communication do function. The theoretical part will introduces the functioning of voice gateways, digital transmission networks, standards (eg. ISDN) and protocols used in these networks (RTP, SRTP, H.323, SIP MGCP, SCCP). We will introduce the key features and functions of Call Manager Express (CME) and Cisco Unified Border Element (CUBE), dial plan, digit-manipulation, and basic troubleshooting. Participants will try the configuration of CME in a practical part where they will simulate configuration for common use of such a gateway. We will present endpoints for audio and video, their features and how do they register with central control elements.
