VoIP Deployment Models in Service Provider Networks

Chapter Description

This chapter gives you an understanding of how Voice over IP (VoIP) is deployed in service provider (SP) networks by describing a use case in which the VoIP infrastructure and the transport and the access are managed by an SP.


This chapter described some of the common SP voice deployment models that are deployed by major SPs in the United States and around the world. These networks are evolving, and a mind-set needs to be created for identifying a key performance indicator (KPI) across these networks. Thinking at the protocol layers and identifying network elements that can be collection points for these protocols are the key. After these KPIs are identified, monitoring them through a series of dashboards allows the SP to effectively manage its services.
