Up to 10 CA Client users can perform login procedures at the sametime. Therefore, when users are connecting to CA Server over an IP network connection, ensure there is 5.0Mbps bandwidth available at all times.Once a CA Client user is connected to a CA Server, the bandwidth required for CA processes is negligible.However, when a CA Client user is connecting to a CA Server that is not within the user’s Local Area Network(LAN), the Auto Absent Message feature in CA Client should not be used. This feature requires significantbandwidth that may affect network performance over connections that are not within a LAN.PBXTo use CA Server, your PBX must have the correct software file version installed.
