摘要
Disclosed are a VoIP server apparatus and a method for maintaining VoIP server software in the server apparatus which transmits/receives a packet to/from an IP terminal via network to provide VoIP service. The method includes: assigning a virtual IP address to the server apparatus; associating a first IP address used by first VoIP server software with the virtual IP address; activating second VoIP server software while the first VoIP server software receives a packet addressed to the virtual IP address and provides VoIP service; changing the association of the virtual IP address with the first IP address to association of the virtual IP address with a second IP address used by the second VoIP server software; receiving a packet addressed to the virtual IP address by the second VoIP server software; and changing VoIP service by the first VoIP server software to VoIP service by the second VoIP server software.
