Abstract: Monitoring voice quality passively using line echo cancellation data across a telecommunications network and reporting monitoring data to a central network management system. Network is monitored for potential voice quality issues for pro-active isolation of problems prior to customer complaints about the problems. Line echo cancellation related and non-related data for IP and other networks is gathered and correlated together to provide voice quality assessments of network performance.

Abstract: Monitoring voice quality passively across a telecommunications network and report monitoring data to a central network management system. Network is monitored for potential voice quality issues for pro-active isolation of problems prior to customer complaints about the problems. A wide cross-section of voice quality related data for IP and other networks is gathered and correlated together to provide voice quality assessments of network performance.

Abstract: A device and method for providing real time compensation for packet loss in the transmission of facsimile data over packet networks to avoid the generation of page loss data and the termination of facsimile transmission. Facsimile devices have a low tolerance for interruptions in transmission. Packet networks commonly have a transmission interruption rate above the tolerance of facsimile equipment. In order to compensate for transmission interruption, the present invention teaches the buffering of facsimile data by scan line at the receiving end, the evaluation of buffered scan lines for packet loss and the discarding of scan lines having packet loss to conceal the packet loss from the receiving facsimile equipment to avoid detection of page errors by the receiving facsimile equipment which could cause loss of facsimile transmission.

Abstract: Gracefully forcing two V.34 fax devices to use legacy G3 modulations (e,g., V.21, V.27ter, V.29, V.17) when communicating over a packet network (e.g, voice over Internet Protocol (VoIP)network). To force an originating fax terminal 10 and receiving fax terminal 18 to fallback to legacy modulation procedures, transmission of a Call Menu (CM) “FAX” signal 54 transmitted by the originating fax device 10 is suppressed S38 at either the originating VoIP/FoIP gateway 12 or answering VoIP/FoIP gateway 16. The suppression of the CM signal 54 forces the answering V.34 fax device 18 to timeout and fallback to non-V.34 fax modulations S40 as if the calling terminal 10 was not V.34-capable. Likewise, upon detecting the non-V.34 fax signals, the originating V.34 fax device 10 will fallback to non-V.34 fax procedures S42. The two V.34 fax terminals will continue the fax transmission using non-V.34 modulations S44.

Abstract: A fax-aware telephone for handling facsimile transmissions over a computer network, such as the Internet, that includes a facsimile processing unit for handling an incoming or outgoing facsimile call, a voice processing unit for handling an incoming or outgoing voice call, a memory unit for storing an incoming facsimile transmission, and a file transfer protocol client for transferring a facsimile transmission to the computer network, an external storage device, or to a printer driver. The fax-aware telephone handles a facsimile call and a voice call together over a single data line from a computer network.
