Communication Manager can establish VoIP media for H.323 stations and trunks, for inter Port Network, gateway or Avaya Aura® Media Server IP connections and for non-Session Manager routed SIP trunks. These IP media connections are not visible to Session Manager. In Communication Manager 7.1, Session Manager can be configured as a central authority for bandwidth management. With this setting, Communication Manager requires bandwidth for voice and multimedia IP connections from Session Manager. You can set the bandwidth limits applicable for various locations through System Manager. For more information about setting bandwidth limits, see Administering Avaya Aura® Session Manager.
