Abstract:
A network terminal apparatus in a type of directly connecting to a packet communication network, with an interface for connecting to a circuit under an environment of an SIP terminal network, and a capability of carrying out facsimile transmission/reception, carries out a call control method according to SIP, transmits and receives an SDP added to a message body of an SIP, and carries out, in a same session, both a call control session transmitting and receiving an SIP message and an SDP and a T.38 session transmitting and receiving a T.38 signal.
Abstract:
According to the data amount stored in a jitter buffer, which temporarily stores obtained data from a received voice packet, an operation timing of an output process of the jitter buffer and a data process of a codec and a modem is adjusted, the codec and the modem processing data that is sequentially output from the jitter buffer.
Abstract:
A device for processing voice and data in a remote access server which provides a voice and facsimile data transmission service over the Internet. The device comprises a first interface for interfacing with a public network; a second interface for interfacing with the Internet; and, a remote access server connected to the first and second interfaces for transmitting voice and facsimile data received from the first interface to the Internet via the second interface and for transmitting voice and facsimile data received from the second interface to the public network via the first interface. The remote access server includes a plurality of voice/facsimile codecs each having a plurality of channels connected to the first interface for encoding and decoding voice and facsimile data provided from the first and second interface; a codec controller for controlling the associated voice/facsimile codecs and for controlling the generation of an interrupt in the corresponding voice/facsimile codec according to whether to process the voice and facsimile data received through the channels; a slave processor for providing the voice and facsimile data to a specified channel, for outputting the voice and facsimile data encoded by the voice/facsimile codecs upon receipt of the interrupt, for decoding the voice and facsimile data provided from the second interface and outputting the decoded voice and facsimile data to the first interface; and, a master processor for communicating with a system operator and for managing the slave processors.
Abstract:
A method for accessing and browsing the internet through the use of a telephone and the associated DTMF signals is disclosed. The preferred embodiment of the present invention provides a system for converting the information content of a web page from text to speech providing the voice signals (voice signals), and to the users receiving DTMF signals from the user corresponding to the hyperlink selections. Upon receiving a DTMF signal corresponding to a hyperlink, the corresponding web page is fetched and again read back to the user.
Abstract:
An Internet facsimile machine provides a voice mail function of transmitting or receiving voice mail together with a document or voice mail only using an electronic mail transmitting and receiving method and includes a scanner to scan a document to be transmitted, a voice signal processing unit to convert a voice message to be transmitted into digital voice data, a signal conversion unit to convert the scanned document data and/or the digitized voice message to be suitable for an electronic mail transfer standard, and a signal transmission unit to transmit the converted document and/or the converted voice message through the Internet. Accordingly, voice data in addition to a document or image data can be transmitted or received by an Internet facsimile machine or a PC connected to the Internet facsimile machine, thereby offering convenience to users.
Abstract:
A Message Storage and Deliver System (MSDS) is connected to the public switched telephone network (PSTN) and receives incoming calls with these calls being facsimile, voice, or data transmissions. The MSDS detects the type of call and stores the message signal in a database. The MSDS is also connected to the Internet and has a hyper-text transfer protocol deamon (HTTPD) for receiving requests from users. The HTTPD forwards requests for certain files or messages to a network server which transmits at least part of the message to the HTTPD and then to the user. In addition to requests for certain documents, the HTTPD may also receive a request in the form of a search query. The search query is forwarded from the HTTPD to an application program for conducting the search of the database. The results of the search are forwarded through the HTTPD to the user. The user may then select one or more files or messages from the search results and may save the search for later reference.
