A communication device has a data application and a voice application. The device establishes a data session between the data application and a data system. During the data session, the device receives a voice session request from a voice communication system, and in response, alerts the user of the request. The device receives a user acceptance of the voice session request, and in response, transfers a voice session acceptance indication from the voice application to the data application and tracks elapsed time since the user acceptance. The communication device transfers a voice session acceptance from the voice application to the voice communication system if the voice application receives a data application ready indication from the data application or if the elapsed time since the user acceptance reaches a set time period, whichever occurs first.
