| 20090154660 | VOICE MAIL APPARATUS AND CONTROL METHOD OF VOICE MAIL APPARATUS - According to one embodiment, a voice mail apparatus includes a voice processor which processes voice messages by a arbitrary processing gain, a gain controller which monitors a signal level of an output signal of the voice processor, and controls the processing gain of the voice processor to change the signal level into a specified level, and a processing controller which makes the gain controller to perform gain control of a learning voice by inputting a portion of the voice message into the voice processor as the learning voice when processing of the voice message is requested or based on predetermined conditions. | 06-18-2009 |
| 20090154661 | VOICE MAIL APPARATUS AND CONTROL METHOD OF VOICE MAIL APPARATUS - According to one embodiment, a voice mail apparatus includes a first determining module which determines whether a dual tone multi frequency (DTMF) signal for identifying a processing request of the voice message is contained in a received signal by detecting and comparing a first parameter of a transmission signal from the mail box and the first parameter of the received signal to the mail box, a second determining module which determines whether the DTMF signal is contained in the received signal by detecting and comparing a second parameter of the transmission signal from the mail box and the second parameter of the received signal to the mail box, and a controller which controls execution/stop of processing of the voice message based on a determination result by the second determining module. | 06-18-2009 |
| 20090268719 | Telephone System and Terminal Device Therein - According to one embodiment, a telephone system comprises a plurality of terminal devices and a main unit. The terminal device realizes telephone communication via a packet-switched network. The main unit accommodates the terminal devices via the packet-switched network. Each of the terminal device comprises an update module, a storing unit, a read module and an access module. The update module updates firmware functioning inside the device in accordance with an instruction from the main unit. The storing unit stores access information for accessing an ante-unit, to which the terminal device is currently connected, before update of the firmware. The read module reads the access information from the storing unit after update of the firmware if an post-unit to which the terminal device is to be connected under the updated firmware differs from the ante-unit. The access module which accesses the ante-unit by using the read access information. | 10-29-2009 |
| 20100106843 | Communication System and its Communication Control Method - According to one embodiment, a communication system comprises a plurality of communication devices connected to a communication network. The plurality of communication devices each comprises a negotiation module and a shifting module. The negotiation module determines a CODEC to be used for a peer to peer communication by notifying a priority order of a plurality of CODECs from a transmitter side to a receiver side in negotiation prior to start of the peer to peer communication. The shifting module shifts the priority order of CODECs based on a predetermined standard to optimize a quality of the peer to peer communication. | 04-29-2010 |
| 20100241754 | Telephone System, Server, and Terminal Device - According to one embodiment, there is provided a telephone system comprises terminal devices which process a signaling protocol, and a server which forms a session with each terminal device using a first protocol or a second protocol as a lower layer protocol of the signaling protocol. The terminal device comprises request module requests the server to form a session using the first protocol. The server comprises determination module, session forming module and switching module. The determination module determines permission or rejection to the request. The session forming module forms a session with a request source terminal device using the first protocol when the request is permitted, or using the second protocol when the request is rejected. The switching module switches the lower layer protocol of the session from the second protocol to the first protocol when the request from the terminal device is permitted. | 09-23-2010 |
| 20110261808 | Server Apparatus and DTMF Notification Method - According to one embodiment, a server apparatus includes a detector and a controller. The detector detects a dual tone multi frequency (DTMF) notification event sent from a communication partner server apparatus in a state that voice communication is performed between telephone terminals by way of a plurality of server apparatuses. The controller executes at least one of a change of a payload type included in a header of a received communication packet and a replacement of a payload data of the communication packet with a DTMF data, based on a detection result by the detector. | 10-27-2011 |
