Cisco to announce SIP integration in all VoIP products

By Derek Sooman on
Cisco systems is expected to make an announcement about integration of Session Initiation Protocol (SIP) into all of the company's future voice-over-IP products some time tomorrow. SIP, a signalling protocol for Internet conferencing, telephony, presence, events notification and instant messaging, is also an IETF standard that enables VoIP products to recognize point-of-presence, IP-based conferencing, and instant messaging capabilities already used by other VoIP components.
