Multimodal telephone calls

摘要

A first computing device, computer readable medium, and a method implemented on a first computing device for establishing a multimodal telephone call. In one aspect, the method includes, on the first computing device, receiving a first request message from a second computing device to register a data session for the second computing device, the first request message including a first telephone number and a second telephone number; on the first computing device, receiving a second request message to register the data session for a third computing device, the second request message including a third telephone number and a fourth telephone number; on the first computing device, determining whether the first and second telephone numbers in the first request message match telephone numbers in other received request messages; and on the first computing device, when it is determined that the telephone numbers from the second computing device and the third computing device match, creating a key for the data session between the second computing device and the third computing device, the key providing a unique identifier for the data session. WO 2012/078381 PCT/US2011/062169 802,, At a multimodal register server computer, receive a first request from a caller computing device to register a data session for the caller computing device At the multimodal register server computer, receive a second request from a recipient computing device to register a data session for the recipient computing device At the multimodal register server computer, determine whether a telephone number from the first request matches a telephone number from the second request Match Detected NO -* 810, At the multimodal register server computer, create an identifier for a data session between the caller computing device and the recipient computing device via the multimodal register server computer
