Yeah, there's so many moving parts to the voice quality equation within the supply chain, equipment choices, and network engineering that it would be hard to even scratch the surface in a mailing list thread. On 6/14/21 12:26 PM, Brandon Svec via VoiceOps wrote:
There are so many places that poor call quality can be introduced?that I suppose someone could write a book about it :)
I do have a general sense that some voice providers, particularly the largest, do some "proprietary magic" for lack of a better term.? For example, RingCentral explains somewhere that they transmit?copies of your voice packets on diverse paths that are monitored carefully and can dynamically switch to the best path during a call with little to no noticeable?call quality changes.? I always thought?that was a pretty novel and a good idea.? I suppose there is a similar?reason that Zoom will tend to work fine where all else being equal another similar platform will not perform well.

I should add that my initial intent was the voice ecosystem, aside from the end-users. For those, usually it's one of the things we all already know.
Why would carrier A have "good quality", while carrier B didn't?
I had a conversation with a customer about quality being more important than price. A lot of things come to mind right away (such as diversity, latency, jitter, packet loss, etc.), but I'm looking for what I don't know.
orrrr
Are there just that many poorly ran companies where the low-hanging fruit I'm brushing aside is where almost all of the problems occur?

I've heard a variety of complaints and concerns over the years about call quality. How are these quality issues introduced? As long as pipes and equipment aren't overloaded, where is a quality issue to come from?
Obviously, the closer you are to the handsets, the less opportunity there is for issues. What else is there to take into account?
