An apparatus for facilitating instant messaging communications between clients of different instant messaging service provider networks is provided. The apparatus includes translation logic for translating received communications related to an instant messaging service, the received communications associated with an external instant messaging service provider network and formatted according to a secondary protocol. The translation logic translates the received communication from the secondary protocol to a primary protocol, the primary protocol native to a receiving service provider network. The communication may then be routed to a client of the primary network according to the native, primary protocol.

Instant messaging interoperability between disparate service providers

Gateway apparatus for facilitating communications using a stateful protocol (e.g., SIP or SIP/SIMPLE protocol). The gateway apparatus includes a plurality of gateway devices and a remote dialog store, wherein each of the plurality of gateway devices comprises export logic for causing dialog information associated with a first received message (e.g., a request or response) to be communicated to the dialog store, and retrieval logic for causing a lookup of the dialog information in response to a second received message, the second received message associated with the first received message. In one example the gateway devices are stateless, thereby relying on the dialog store for validating and routing messages. In another example, the gateway devices are stateful and rely on the dialog store for backup (e.g., if a gateway device crashes). The gateway devices may be configured for receiving and processing messages according to SIP protocol or SIP/SIMPLE protocol.
