A method and system for prioritizing data packets relating to a conversation over a VoIP communication channel is provided. An individual client or a service provider may specify priority information corresponding to incoming conversations. When several calling clients send data packets to one called client, the predefine priority information of the called client may be exchanged as part of contextual information. Based on the predefined priority information, priority levels are assigned to the received data packets. Subsequently, an existing communication channel may be terminated, interrupted, altered, and/or suspended in order to transmit data packets with higher priority than other data packets. A new communication channel may be established for a two-way communication, or a one-way communication between two clients. In this manner, the highest priority conversation among several incoming conversations, such as an emergency broadcast message or communication, can be ensured to reach to a client without a delay.
