摘要:
A method of controlling a codec negotiation of a gateway (1) providing a codec capability offer, e.g. OLC according to the standard H.245, for establishing a data connection (1A, NA, 5T, 12T) to a communication device (10), comprises the gateway (1) providing a DSP resource (5A, 5B) for encoding (C1E) and/or decoding (C1D) of data to be transmitted using a codec which is negotiated between the gateway (1) and the communication device (10), and controlling the gateway (1) to limit (4B1, 4B2, CA2, CA14) a selection of codecs available at the gateway (1) from at least two codecs reserving different amounts of the DSP resource (5A, 5B) respectively, to be included in the codec capability offer to a codec which reserves the least amount of the DSP resource (5A, 5B) such that the communication device (10) is forced (CA4, CA15) to select the codec which reserves the least amount of the DSP resource (5A, 5B).

An origination terminal UA100 according to the present invention is provided with a screen state memory unit 500 for storing a screen state of an information display unit 360 at transmission of a call request including information on communication on a desired network and an initiation state of an application corresponding to the screen state and a control unit 320 for controlling the information display unit 360, when receiving a call enable notification in response to a call enable notification request transmitted after cancellation of a call from a destination terminal UA200, which becomes able to use the desired network, to display the screen state stored in the screen state memory unit 500 and, when detecting a call instruction in the screen state, an application corresponding to the call instruction to send a call.
摘要:
Un serveur de messagerie vocale (VM) selon l'invention met en oeuvre les étapes consistant à déterminer préalablement au dépôt d'un message vocal par le terminal (T_A) d'un utilisateur, si un terminal audio (T_B) de l'utilisateur abonné audit serveur utilise couramment au moins un codeur audio fonctionnant dans une première bande de fréquence prédéterminée ou au moins un codeur audio fonctionnant dans une deuxième bande de fréquence prédéterminée, puis à identifier (E2), lors du dépôt du message vocal par ledit terminal audio (T_A), les codeurs audio susceptibles d'être utilisés par ce terminal audio. Si au moins deux codeurs audio identifiés fonctionnent respectivement dans les première et deuxième bandes de fréquence prédéterminées, ledit serveur sélectionne (SE3a) à partir dudit terminal (T_A), le codeur audio fonctionnant dans ladite première bande de fréquence, si ledit serveur a préalablement déterminé que le terminal de l'utilisateur abonné utilise couramment un codeur audio fonctionnant dans la première bande de fréquence prédéterminée, ou bien sélectionne (SE3b ou SE4) à partir dudit terminal (T_A), le codeur audio fonctionnant dans la deuxième bande de fréquence si ledit serveur a préalablement déterminé que le terminal de l'utilisateur abonné utilise couramment un codeur audio fonctionnant dans la deuxième bande de fréquence prédéterminée. Puis ledit serveur enregistre (E4) le message vocal déposé, dans le format de codage conforme au codeur audio qui a été sélectionné à partir dudit terminal (T_A).
摘要:
Various technologies and techniques are disclosed that improve media communications. In one embodiment, a media server receives a media communication with a first quality from a personal computer with VoIP telephone capabilities. The media server translates the media (e.g., audio, visual, etc.) communication into a second quality, and forwards the media communication to a communication gateway. The translation to improve communications can also be done when receiving the media communication from the communication gateway for forwarding to the personal computer having VoIP telephone capability. In some embodiments, a media server sits in the communication channel between a personal computer with VoIP telephone capabilities and a communication gateway and is able to translate communications into codec protocols they each understand.

According to the invention, in order to transmit user data from a source communications device (KE1) provided with a first encoder (CODEC_A, CODEC_B1, CODEC_C) for encoding users data to a target communications device (KE2) provided with a first decoder (CODEC_J2, CODEC_K) for decoding said user data via a communication network which is provided with several converting devices (GW1, GW2, GW3) comprising additional encoders (CODEC_B2, CODEC_D, CODEC_H2,...) and additional decoders (CODEC_B2, CODEC_D, CODEC_H2,...) for carrying out the verification of the converting devices (GW1, GW2, GW3). Said verification consists in determining, whether the first encoder (CODEC_A, CODEC_B1, CODEC_C) is compatible with the decoder (CODEC_B2, CODEC_D, CODEC_H2,...) of a given converting device (GW1, GW2, GW3) and, whether the first decoder (CODEC_J2, CODEC_K) is compatible with the encoder (CODEC_B2, CODEC_D, CODEC_H2,...) of said converting device (GW1, GW2, GW3). One of the converting devices (GW1, GW2, GW3) for which the compatibility is ascertained by the verification is selected for transmitting user data. During transmission of the user data, said user data encoded with the aid of the first encoder (CODEC_A, CODEC_B1, CODEC_C) is decoded with the aid of the compatible decoder (CODEC_B2, CODEC_D, CODEC_H2,...) of the converting device (GW1, GW2, GW3) and the user data decodable with the aid of the first decoder (CODEC_J2, CODEC_K) is encoded with the aid of the compatible encoder (CODEC_B2, CODEC_D, CODEC_H2,...) of the selected converting device (GW1, GW2, GW3).
摘要:
IMS networks and methods are disclosed for providing a call response service for businesses. Businesses that subscribe to the call response service may implement a call response system that is operable to provide multimedia responses. When the IMS network receives call signaling for a call to the business, the IMS network determines whether the calling party device supports multimedia responses. The IMS network then instructs or informs the call response system to provide the proper type of response (multimedia or voice) to the calling party device based on the determination of whether or not the calling party device supports multimedia responses.
