Title
(EN) SYSTEM AND METHOD FOR HANDOFF OF SESSION FROM VOIP INTERFACE TO CELLULAR INTERFACE OF DUAL-MODE DEVICE
(FR) SYSTÈME ET PROCÉDÉ POUR UN TRANSFERT DE SESSION D'UNE INTERFACE VOIP À UNE INTERFACE CELLULAIRE D'UN DISPOSITIF BI-MODE
Abstract
(EN)
A method and system for handing off an active VoIP call with a remote party from a VoIP interface of a dual-mode device to a cellular interface of the dual-mode device. A cellular call is established between a PBX IP/PSTN gateway and the cellular interface. Media relating to the first termination point of the VoIP leg of the active call is then redirected to the cellular call and the VoIP leg is terminated.
(FR)
L'invention concerne un procédé et un système pour transférer une communication VOIP active avec un correspondant distant d'une interface VoIP d'un dispositif bi-mode à une interface cellulaire du dispositif bi-mode. Une communication cellulaire est établie entre une passerelle PBX IP/PSTN et l'interface cellulaire. Des supports relatifs au premier point de terminaison de la branche VoIP de la communication active sont ensuite redirigés vers la communication cellulaire et la branche VoIP est coupée.
