摘要

A method for establishing a multimodal telephone call is provided. On a first computing device, a telephone call is received from a second computing device. On the first computing device, a response is sent to the second computing device that a telephony session is established between the first computing device and the second computing device. On the first computing device, a request message is sent to register the first computing device for a data session at an online registry service. On the first computing device, a response message is received indicating that the first computing device is registered at the online registry service. The response message includes a key that uniquely identifies the data session. On the first computing device, the key is used to establish the data session with the second computing device.
