1. A number of software services
are supported by each server
2. An instance of a VoIP system
may comprise a number of
individual software services
3. VoIP systems are organized
into redundancy groups that
supply services
4. Virtual software service allows
correlation of events at group
level
5. Some services are not
associated with a single VoIP
system
6. Hardware can be directly
included in the service
7. Media gateways are related to
software services registered
with media server
8. Service depends on hardware
and software
9. Groups of IP phones are
associated to services

VoIP Service Management Objectives
IP Telephony Users
• Auto-discover the physical, logical and virtual entities and relationships
• Monitor availability and performance attributes
• Correlate the end to end service relationships – networks, servers,
applications and storage – that impact VoIP
• Automate root cause analysis of problems at all layers
• Correlate the user experience (QoE/QoS and the end to end service
relationships
• Calculate the impact of problems on related infrastructure elements
• Correlate infrastructure impacts on business services and users
• Automatically adapt to changes
