Abstract:
A system and method in which a notification is received of a call from a first device to a second device in a first domain. A context is created for the first type of call. A notification is received of initiation of a call from the second device to the first device in a second domain. The call context is utilized to notify the first device of the initiation of the call from the second device to the first device.
Abstract:
A method for routing a plurality of calls to a single endpoint of a plurality of endpoints at a common destination is disclosed. The method comprising the steps of: initiating (202) a call over a first network (118) having a first network type, the call being directed to a destination (106) that has a plurality of endpoints 108, 110, 112, 114. Establishing (204) the call over the first network with a first final endpoint (108) of the plurality of endpoints. Receiving (206) a temporary endpoint identifier. Initiating (208) a second call to the destination by sending a request message for a second call of a second network (120), having a second network type, the request message including the temporary endpoint identifier. Establishing (210) the second call, simultaneously with the first call, over the second network with the same final endpoint.
Abstract:
The present invention provides a communication system and a method for redirecting a call to a call destination between multiple different operating modes. An attempt to establish a communication connection with the call destination is made via a first operating mode. Upon receipt of a rejection of the attempt to establish a communication connection, a determination is made as to a second operating mode, which is different from the first operating mode, that is capable of supporting a communication with the call destination via a communication connection. A type of call data for the call is then converted from a type corresponding to the first operating mode to a type corresponding to the second operating mode, and the call data of the call having the converted type corresponding to the second operating mode is communicated using a communication connection established with the call destination via the second operating mode.
