Testing SIP and VoIP Quality Using N2X
Key Features
- Highly scalable SIP emulation (10k active SIP sessions per test port)
- True Multiplay test solution: VoIP, Video and Data on the same port
- MOS estimatesrt
Test Objective
This application note shows how N2X can be used to test a device or network’s ability to provide adequate VoIP QoS. SIP sessions will be established over an underlying access protocol. We will measure the SIP scale and performance the device under test (DUT) can support. Once SIP sessions are in place, we will generate simulated VoIP service traffic. N2X will then be used to make delay and loss measurements on the traffic. MOS measurements will also be used in order to approximate the perceived VoIP quality and ultimately render a verdict on whether the DUT is delivering acceptable QoS.
