SIP/H.323 Interconnection
SIP-based devices cannot communicate with H.323.supporting devices directly, but
through a SIP/H.323 gateway. This gateway transfers signalling messages from/to the
protocols. Using the RTP for multimedia data transmission, the SIP and H.323
protocols can go on communicating directly when the SIP/H.323 gateway connection
is established. Thus, the SIP/H.323 gateway helps integrate
into
2N VoiceBlue MAX

the existing H.323 environment.
