    Abstract: A system and method allow a user of a parallel cordless handset to join in an ongoing communication. A conference circuit is placed on the ongoing conversation and the parallel handset is bridged into the conversation. The system and method can also bridge in data transmissions. An alert can provide notification to the handset already in the conversation, the handset attempting to join the conversation, or both. The system can be set up to allow access to the conversation upon election of either handset user or, alternatively, upon election of both handset users. Alternatively, the access can be granted without requiring election (automatically) or can be mandatory. More than one handset can be joined into the ongoing communication.
