A Bit of History ………… • 10 years ago, there were only traditional PBXs. Today, the market would still be traditional PBXs if Cisco didn’t disrupt that market and build something better on an IP core. • To disrupt this market, Cisco’s first focus was to compete with PBX manufactures on their level Build an IP-PBX equivalent to any PBX on the market. • At the time Cisco began work on Cisco Unified Call. Manager, standardizing Vo. IP protocols were too immature to replicate PBX features. Cisco had to develop SCCP protocol to address the difficult issues and build that IP-PBX. At the same time, we also have focused on the IETF standards body solving the difficult SIP problems (SIP and SIPING WG leads, RFCs, etc…). • SIP is now ready to support the services and capabilities for the Cisco Unified Communication system Session Number Presentation_ID © 2005 Cisco Systems, Inc.
