Patent

CA 2485624

There is disclosed a private branch exchange in which an SIP terminal is capable of receiving great variety of services provided by the private branch exchange without upgrading version of software of the SIP terminal itself. A standard SIP protocol control module 16, an expanded SIP protocol a control module 17, and an expanded SIP protocol b control module 18 are disposed for SIP system protocol corresponding terminals, convert signals (requests) from the SIP system protocol corresponding terminals into signals of a protocol inside an IP-PBX 1 to transmit the signals to a PBX basic connection process providing module 12, and convert a signal (responses to the request, or a request to the SIP system protocol corresponding terminal) from the PBX basic connection process providing module 12 into a signal of an SIP system protocol to transmit the signal to the SIP system protocol corresponding terminal.

La présente invention décrit un autocommutateur privé où un terminal SIP est capable de recevoir une grande variété de services fournis par un autocommutateur privé sans avoir à mettre à jour la version logicielle du terminal SIP proprement dit. Un module de contrôle de protocole SIP normalisé (16), un module de contrôle du protocole SIP a élargi (17), et un module de contrôle du protocole SIP b élargi sont placés pour les terminaux correspondants au protocole du système SIP, convertissent les signaux (demandes) des terminaux correspondants au protocole du système SIP en signaux d'un protocole dans un IP-PBX 1 pour transmettre les signaux au module assurant le traitement de la connexion PBX de base (12) et convertissent un signal (réponses à la demande, ou une demande au terminal correspondant au protocole du système SIP) du module assurant le traitement de la connexion de base PBX (12) en un signal du protocole du système PIB pour la transmission du signal au terminal correspondant au protocole du système SIP.
