On a fully time division multiplexed (read: no IP packets; just end-to-end multiplexed serial streams) call, it should be no more than ~40 milliseconds of latency from one side of the United States to the next, or no more than quantization delay from the g.711 codec (0.125 milliseconds) when simply traversing the bus of the local switch.
Thankfully, there's discounts stashed here and there for landline phones. Some are easier to get than others, though, and it definitely doesn't help that like with anything else from a telco, the price keeps getting jacked up.
- emanuensis 7y agoVery very revealing! Thanks! i would assume that VoIP calling would suffer from the same "packet switching" issue that mobile telephones do:-(( With the current emergency caused by the corona virus there is a huge up tick in remote work. A whole sector of this suffers immensely from "Latency" issues. There is a huge market for the solution of that problem: Choral groups, various meditation practices involving a shared "soundscape", etc. Perhaps a quick solution for the more professional groups with that issue is to require all members to have a "Land Line" and then do a conference call.
