Abstract
Methods, apparatus and computer program products for processing signaling information for telephone call attempts in a packet-based telephony service. An overload protection node is introduced to protect a signaling node from an overload of signaling information for telephone call attempts. A characteristic of signaling information for telephone call attempts in the packet-based telephony service is monitored by the overload protection node and on the basis of the monitored characteristic, the overload protection node processes signaling information for telephone call attempts according to one of a number of different modes of operation. A mode of operation may involve transmitting signaling information for a call attempt to the signaling node or selecting one or more call attempts at the overload protection node for the purpose of reducing overload in the signaling node.
