Resource description

This resource can be incoming or outgoing.If outgoing, the messagingInvitation can be created in one of two ways.First, startMessaging will create a messagingInvitation that also creates a conversation.Second, addMessaging will attempt to add the messaging modality to an existing conversation.This resource assists in keeping track of the invitation status; for example, the invitation could be accepted, declined, or ignored.An outgoing messagingInvitation will be in the 'Connecting' state while waiting for the recipient to accept or decline it; during this time, the messagingInvitation can be terminated using cancel. Note that if the recipient does not respond in approximately thirty seconds, the messagingInvitation will complete with failure.Ultimately, the messagingInvitation will complete with success or failure (in which case a reason is supplied).If the messagingInvitation succeeds, the participant that accepts it will be provided (acceptedByParticipant).If incoming, the messagingInvitation can create a new conversation or attempt to add the messaging modality to an existing conversation.
