A method and apparatus for increasing call capacity in a packet switched telephony system in an emergency mode. The telephony system includes a management system, which detects an emergency, such as a surge in incoming media streams, a surge in traffic elsewhere in the system, a potential surge in traffic, and/or a convention emergency situation such as a natural disaster that may cause a surge in traffic. The management system alerts an internet telephony machine, such as a gateway, to the congestion problem. The internet telephony machine responds by switching to a lower bandwidth coder, thereby outputting each incoming media stream at a lower output rate, and thereby effectively increasing the capacity of the receive and handle calls.
