Abstract: There are disclosed systems and methods for correlating a data collaboration session between at least two clients via a third client on a network. The method comprises providing a first, second and third client with a unique identifier and establishing a communication in an audio channel between the first and third clients The established communication in the audio channel is forwarded to the second client. The method further comprises signalling by the first client to the second client a request for a data collaboration session, responding to the signal by the first client by sending the unique identifier of the second client to the first client via the audio channel, associating the unique identifier of the second client with the communication and associating the identifier of the first client with the communication. The method further comprises transferring the associated identifiers of the first and second clients to a server configured for holding the data collaboration session.

Abstract: A facsimile gateway provides fax transmission over a packetized network. To accommodate packet delay in the network, an alternate protocol source provides the appropriate notifications to the originating fax machine. In one embodiment, the gateway is constructed using conventional class II or 2.0 fax/modems and voice processing boards. The fax board provides most of the fax gateway operations. As needed, the voice board is switched into the call to provide notifications to prevent a time-out in the originating fax machine.
