Is there such a thing as a 'high call quality' VoIP service provider or is VoIP just VoIP?
In a way Voip is a way to packetize sampled (and may be coded) voice in IP packets and
send them over to other end of the call.
However, Voip as a service definitely varies a lot across providers.
So some of the metrics/aspects that characterize a provider include (but not limited) to:
+ quality of routes: you want low latency and near zero packet losses
+ low latency variability (aka jitter)
+ high service availability: this is sometimes done by provider multiple data path to destinations,
support redundant call servers, redundant peering points, etc etc
+ cost
There are several posts in here that makes references to providers of varying degrees of quality.
In my case i use couple of the so called Betamax companies (Easyvoip and VoipaLot).
And I also use Voxbeam. The former ones are really cheap, they work ok but the service quality may
vary at times. Voxbeam seem to provide a lot higher quality routes but that comes at a cost premium.
If you search this forum you'll find quite a few discussions and references to providers.
