How would you best learn VoIP Quality of Experience ?
Before diving into packet loss and jitter, I would like to know what a toll-quality call is, what a rated 3.5 MOS call is like.
I'm wondering how I should proceed.
Shall I :
- get pre-recorded sound files somewhere and simply stream them to a MOS enabled softphone (Counterpath sells eye-beam which includes a telchemy MOS rating module),
- or shall I install some network impairment software, generate VoIP trafic and tweak myself jitter and other parameters so that I can associate network measures to call quality ?
I've never heard of any sound files library aimed to learn what the impact of packet is like for end user experience.
I've seen here and there network simulators (some of them free of charge) but it seems tricky to tune them to VoIP (is a 10% packet loss realistic or not ?).
To make myself perfectly clear, my ultimate goal is to better undestand users testimonies when they warn me about poor quality phone calls.
Regards
