• VŠE Prague, connected through ISDN/PRI in December 2002• University of Ostrava, connected through ISDN/BRI (to be completed inJanuary 2003)The project researchers have also participated in the process of connectiondesigning and carried out configurations of the access VoGW. The purchaseand selection of a supplier of required equipment is ensured directly by theapplicant.We recommend using an explicit prefix for an access in the IP telephony. Inaddition, the service availability is being successfully tested in order to allowreliable automatic call routing.In September 2002, we changed the numbers in the IP telephony network, inline with the changes in the numbering plan of the Czech public telephonynetwork.CTU/ICHT/CESNET 42022435xxxxCESNET4202259815xxCU Praha, rector‘s office 420224491xxxTU Ostrava42059699xxxx, 42059732xxxxSLU Opava420596398xxxSLU OPF Karviná420553684xxxUniversity of Pardubice 420466036xxx, 420466037xxx, 420466038xxxTU Liberec42048535xxxxMU Brno420541512xxxBrno UT42054114xxxxCU FPh, Hradec Králové 420495067xxxUniversity of Hradec Králové 420495061xxxUniv. of South Bohemia 42038777xxxx, 42038903xxxxUniv. of Economics Praha 420224905xxxUniversity of Ostrava 420596160xxxPU Olomouc42058563xxxx, 42058732xxxx, 42058744xxxxCAS, Inst. of Physics Praha 420266059999For internal needs 42076xxxxxxxFigure 8.2: Free inland phone numbersCERN (www.cern.ch)Fermilab (www.fnal.gov)SLAC (www.slac.stanford.edu)412276xxxxx1630840xxxx1650926xxxxTable 8.3: Free international phone numbersFor the currently valid list of free dial numbers, visit www.cesnet.cz.110 High-speed National Research Network and its New Applications 2002
VoGWs of members involved in the project are usually connected via ISDN,which allows for the storage of detailed records concerning the calls in the SQLdatabase on the RADIUS server. The IP telephony network has been orientedon the H.323 protocol (min. version 2). The internal elements of the VoGW andGK (Gatekeeper) network are based on the Cisco platform, which proved to bebeneficial with respect to the extension and management of the network.CESNET2GKOstravaGKPrahaCERN412276xxxxxGKAliatelSLAC1650926xxxxCesnet-extLinux GKAARNET61xxxxFigure 8.2: Scheme of interconnection among control elementsFor purposes of foreign H.323 connectivity of other entities, there is the externalLinux GK located in Prague. As regards the hierarchy, this GK is linked over theinternal GKs in Ostrava and Prague. Each internal GK is provided with a backupand all GWs in the network log in to both elements with a priority according totheir geographic location. In the usual operation mode, logging with a higherpriority is active. The requirements for calls outside VoIP network of CESNET2are rerouted by the Internet (NIX.CZ) to the Aliatel GK.Figure 8.3 shows a scheme of the IP telephony network. Many thousands of usersconnected to private exchange branches have access to the services afterdialling the required prefix. Dialing in CESNET2 is carried out according to thepublic numbering plan, in accordance with the valid telephone directory (without420). For international calls, 00 is dialled before the code of the country, e.g.,0043 for Austria.High-speed National Research Network and its New Applications 2002111
