Abstract
A radio communications device has a memory having stored therein a user application program (16), a telephony program (18) and an application programming interface (API) 30 between these. Various aspects of the API are described. In one aspect, the API has a command for establishing a call and the telephony program accepts, as an argument of the command for establishing the call, an array identifying several terminal objects (54-58), thereby permitting establishment of a call for multiple terminal objects. In another aspect, groupings of events are described and an API command defines an event class from one of the groups together with an ID defining an event within the event class. In a further aspect, a program in the telephony program is called to create a call object (50). The call object is created regardless of whether radio service for the radio comunications device has been established.
