Abstract: An embodiment of the present invention includes a fax communication system for communicating fax information between a first fax machine having error correction capability and a second fax machine. The first and second fax machines are coupled to communicate with one another across a packet switching network. A network device is coupled to received fax information from the first fax machine and accumulates a portion of the fax information and stalls the second fax machine while accumulating the fax information portion until the latter is transmitted to the second fax machine free of errors across the packet switching network. Accordingly, information traffic across the packet switching network is decreased thereby avoiding a network avalanche effect.

Abstract: The invention provides a way to fallback to a PSTN call at any time during a VoIP call when Quality of Service in a VoIP network falls below some acceptable level. The PSTN fallback calls can be retrieved “midcall” and rerouted back over the VoIP network. This provides optimal utilization of VoIP without sacrificing the quality of the call connection. Calls are cheaper because PSTN fallback calls are only established temporarily for the amount of time that the QoS problem exists on the VoIP network. Call fallback is conducted in a VoIP gateway by first receiving an incoming call. A Voice over IP (VoIP) call is established for the incoming call over the VoIP network. VoIP packets are encoded from the voice signals in the incoming call and sent over the VoIP network. Quality of service of the VoIP network is monitored during the VoIP call and a fallback call is setup over a PSTN network at any time during the VoIP call when the monitored quality of service of the VoIP network degrades. For a time the voice signals from the incoming call are cross connected to both the output for the fallback call and the output for the VoIP call. When a destination gateway starts receiving the voice signals from the fallback call, the VoIP call is dropped. The quality of service on the VoIP network continues to be monitored during the fallback call. A new VoIP call will be reestablished over the VoIP network during the fallback call when the quality of service of the VoIP network improves. Voice from the incoming call is for a time again cross connected to both the fallback call and the new VoIP call. After the destination gateway starts receiving audio packets again over the new VoIP call, the PSTN fallback call is terminated.

Abstract translation: 本发明提供一种在VOIP呼叫期间的任何时间在VoIP网络中的服务质量低于某些可接受的水平时回退到PSTN呼叫的方法。 PSTN回退呼叫可以被检索到“中间呼叫”，并通过VoIP网络重新路由。 这提供了VoIP的最佳利用率，而不牺牲呼叫连接的质量。 呼叫更便宜，因为只有在VoIP网络上存在QoS问题的时间量内暂时建立PSTN回退呼叫。 呼叫回退在VoIP网关中进行，首先接收来电。 通过VoIP网络为呼入建立IP语音（VoIP）呼叫。 VoIP分组根据来电中的语音信号进行编码，并通过VoIP网络发送。 在VoIP呼叫期间监控VoIP网络的服务质量，并且当VoIP网络的监控服务质量下降时，在VoIP呼叫期间的任何时间，通过PSTN网络建立回退呼叫。 一段时间来自来电的语音信号交叉连接到回退呼叫的输出和VoIP呼叫的输出。 当目的地网关从回退呼叫开始接收语音信号时，VoIP呼叫被丢弃。 在后退呼叫期间，VoIP网络上的服务质量继续受到监控。 当VoIP网络的服务质量提高时，在回退呼叫期间，VoIP呼叫将重新建立在VoIP网络上。 来电的语音再次与后退呼叫和新的VoIP呼叫交叉连接。 在目的地网关通过新的VoIP呼叫再次开始接收音频分组之后，终止PSTN回退呼叫。

Abstract: An improved method and system for connecting Super Group 3 fax machines over network gateways that operate using the un-enhanced T.38 protocol. With the present invention, the CM tone is suppressed. Thus a gateway that generates an AnsAm tone, will not receive a CM tone in response. The T.38 protocol does not specify what occurs if a CM tone is not received; however, it has been found that, in practice, existing fax machines fall back to V.21 mode if a CM tone is not received.

Abstract: A call fallback scheme is provided in a packet switched network. After receiving incoming calls, a Voice over IP (VoIP) link is established over a packet switched network with a destination endpoint. VoIP packets are generated from the incoming calls and sent over the VoIP link to the destination endpoint. When a low quality of service condition is detected on the VoIP link with the destination endpoint, a fallback call is established with the destination endpoint over a circuit switched network. The VoIP packets for the incoming calls are redirected from the VoIP link to the circuit switched data link. As opposed to simply hairpinning a TDM voice call back over the PSTN network 102, the same VoIP packets for the incoming calls originally destine for the destination endpoint over the packet switched network are rerouted through the fallback call. This simplifies synchronization with VoIP packets sent over the VoIP network. Because VoIP packets for more than one call can be sent over the fallback call, the cost of maintaining the fallback call is also substantially reduced.
