Presence and Communications
• The primary use for presence
information is to facilitate
communication
• The best way (but not the
only way) to derive presence
information is by monitoring

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 CallManager,
standardizing VoIP 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

Key Guidelines for SIP Integration in Cisco Unified
CallManager 5.0
• Preserve customer investment in Cisco
Unified Communications system
infrastructure during introduction of SIP
based communications
over 7 million phones, over 37,000 IPC customers
• Allow at-your-pace customer migration to
new capabilities
provide seamless interoperability between SIP and SCCP
• Continue to support existing features while
introducing new SIP features
must be feature parity between SIP and SCCP

Guidelines for Presence Integration
Cisco Unified CallManager 5.0
• Presence Integration into the Infrastructure
Allows Presence to be used for both Cisco Unified CallManager internal
features as well as Services in a Presence enabled IP Network
Allows for collection and passing of Cisco Unified CallManager internal
status for any Cisco Unified IP Phone – both SIP and SCCP
• Standards Based using SIMPLE (SIP for
Instant Messaging and Presence Leveraging
Extensions) based
Supports Presence Event Package, Presence Information Data Format
(PDIF), Rich Presence Extensions (RPID)
Allows for Interoperability with any SIMPLE based presence network
• Provide Initial Presence Features
Proof of Presence Integration
Continue to provide more Presence Features to Cisco Unified
CallManager in Future Releases
