Prior to the operation of the system, it would be beneficial to systematically test the system performance to support VoIP operation. Basically, the test is merely sampling the system performance to see if it fits to the design requirement. It may increase our confidence as well as to see any possible problems.
In general, there are several type of testing prior to the operation of the system, namely,
- Test between sites. To see any possible problems due to congestion in the access network or on the wide area network. It would be better if the test can be performed in the long period of time, say one (1) month. Test process can be done by using a simple tools to simulate RTP traffic as router should handle differently as compared to ICMP.
- Pilot trial. Limited test of the planned IP telephony system to see if there would be any problem in full fledge deployment.
- Desktop testing. Our LAN may experiencing a lot of problems, we need to develop a mechanism to test each segment to see how severe the collisions and the packet loss. Use VoIP analyzer to see packet loss and jitter during installation.
