In a system with IP Stations, maximum 50 stations will receive group call by default. This is because the group call audio is by default transmitted using unicast. If there are larger groups than 50 members, group calls must use multicast. (AlphaPro: Exchange & System -> System -> VoIP tab -> Enable "Multicast"). See also: Multicast_in_AlphaCom |
