Chapter 8: Troubleshooting VoIP
A fragmented approach to testing is not effective for supporting a
packet-based service with the stringent performance requirements
of VoIP. A comprehensive end-to-end testing strategy must be
developed to ensure customers’ QoE. It should be comprised of
custom-developed bundled sets of handheld test instruments, test
systems, and test software. The testing strategy should provide an
integrated approach that is coordinated with each stage of VoIP
service delivery.
In addition to providing technicians with the ability to see and hear
how VoIP is performing, test suites should help service providers
anticipate and prevent problems before they occur and escalate
into larger problems—ultimately to reduce expensive backtracking
and troubleshooting. VoIP networks deployed using these
processes and procedures and test methods will provide reliable
consistent service to end customers and operate cost effectively
and profitably for the service providers implementing them.
