IWF Services

Using the Oracle® Enterprise Session Border Controller’s interworking function (IWF), you can interconnect SIP networks with H.323 networks. Considering the large amount of H.323 deployments already in place and the continuing emergence of SIP in new VoIP deployments, the IWF provides a much-needed solution. SIP providers can maintain a single-protocol backbone while exchanging VoIP sessions with H.323 providers.

The H.323 Signaling Services section contains information about the H.323 signaling modes of operation that the Oracle® Enterprise Session Border Controller supports. The following H.323 signaling modes of operation can be used when you use the Oracle® Enterprise Session Border Controller’s IWF in an access or a peering solution.

• Back-to-back gateway signaling
• Interworking gatekeeper/gateway
