Abstract: An approach is provided for supporting telephony services over a data communication network. A network server receives multiple early media streams associated with a communication session between an originating network element and one or more terminating network elements. The network server selectively suppresses the early media streams, such that the originating network element receives a single signaling message indicating status information of the communication session (or call). The present invention has particular applicability to SIP (Session Initiation Protocol) IP (Internet Protocol) telephony services.

Abstract: A system for malicious code detection includes a front-end processor, multiple scanning computer systems, and a detection management system. During operation, the multiple scanning computer systems scan content for malicious code and generate an alarm when the content contains malicious code. The front-end processor receives a flow of content from an external network and distributes copies of the flow to each of the multiple scanning computer systems in parallel for scanning. The detection management system employs a countermeasure on the flow if at least one of the scanning computer systems generates the alarm.
