Network address translation in a VoIP system |
摘要 |
An apparatus and method for voice processing of VoIP are disclosed. The method includes: allowing a call server to perform a VoIP application level gateway (ALG) function and to set a public media gateway address corresponding to a private media gateway address of the call server in a packet data unit (PDU) of a VoIP packet to perform VoIP signaling; allowing the call server to set a private signaling address in an IP header of the VoIP packet and to transmit the corresponding VoIP packet to a data server; and allowing the data server to convert the private signaling address set in the IP header of the VoIP packet received from the call server into a public signaling address and to transmit the converted address to a destination though the Internet. Since the data server does not perform the VoIP ALG function but performs only a network address translation/port translation (NAPT) task for the IP header, a task load due to correction of data set in the PDU may be omitted, so that a quality of the VoIP service may be enhanced.
