Abstract
In the 3rd generation multimedia communication world and in the 3GPP standardization consortium, SIP protocol appears to be the preferred signaling protocol. However, the need to communicate with non-SIP based network, e.g. H.323 from ITU-U, is still a reality. The need can be satisfied with the introduction of network gateways (also named Inter-Working Function). One of the open issues about SIP-H.323 interworking is the address resolution, in other words, the automatic forwarding of a SIP call to an H.323 user. The paper proposes a SIP network architecture which can interoperate with H.323 networks, safeguarding the existing software/hardware components, as SIP terminal clients or SIP server proxies or IWF gateways.
