Pre-connection telephony data synchronization

摘要

A method of transmitting updates to a data requester can include receiving a telephony connectivity request for establishing a telephony voice channel between a data requester and a data source. The data source can be detected based upon the telephony connectivity request. A data synchronizer can ascertain an update time that the data requester last received a data update and can determine a synchronization time that the data source was last synchronized. The data synchronizer can compare the update time and the synchronization time. If the synchronization time occurs after the update time, then the data synchronizer can synchronize the data requester with the data source.
