Abstract
Multiple session initiation protocol (SIP) devices connected to a server via a network may attempt to initiate a process (such as SIP registration) at approximately the same time as each other, by sending SIP messages (e.g. 'REGISTER' messages) towards the server substantially simultaneously. Depending on the number of devices and the resources of the server, the server may not be able to process all of the messages without crashing. An interposed network element, such as a session border controller (SBC), may prevent some of the messages from reaching the server, to stop the server from crashing. However, some messages may be of higher priority than others. The invention provides a way of differentiating between messages to assist in prioritising messages with higher priority over others.
