Hello Dmitry,
On Sunday October 06 2024 19:30, you wrote to me:
MV>> Why can`t you run the system at the location where you are?
DP> Energy prices in the UK are too high and free space is very limited.
So you take the best of both worlds...
DP> It`s also no longer possible to get a home phone
Eh.. ?? You were talking about modem over Voip. That should work in the UK.
DP> and CSD has been disabled on UK GSM networks.
CSD??
[..]
MV>> VOIP is a senseless double conversion. You convert a digital
MV>> signal to audio. And then you encode the audio to a digotal
MV>> signal to transport it. At the other end you do the reverse. It
MV>> is like sitting on a horse in a trailer that is towed by a car.
MV>> It makes sense to do away with the horse and the trailer and just
MV>> use the car to go from A to B.
DP> It`s like HAM radio. Makes little sense if you have mobile phonem but
DP> it`s still fun!
HAM radio keeps working if everything else breaks down. But I am
not going to argue, it is true that cell phones have taken most of
"the magic" out of amateur radio. *1)
DP>>> Too bad it`s not possible to put multiple phone numbers in
DP>>> Nodelist.. I don`t know why The Founding Fathers never thougth
DP>>> about this idea? It`s so inconvenient.
MV>> Inconvenient for who? In the POTS age there never was a need.
DP> For me and my modem friends :)
You and your modem friends are just a small closed group. You can
easely distribute a private list.
MV>> lines were expensive and for most one line was enough. But in de
MV>> POTS age every decent phone company had the option to make
MV>> multiple lines reachable via one phone number.
MV>> VOIP has that possibility too.
DP> What if I want connections to different phone companies?
At the time of the founding fathers that was not an option. So of
course they did not consider that.
DP>>> It`s not POTS, actually. One of the lines is from a GPON box, 2
DP>>> are from GSM CSD, and the rest are from SIP. But it`s still PSTN
DP>>> (because of the E.164 numbers involved), just not POTS.
MV>> Ok, it is not POTS, so it is not really going back to the roots.
MV>> It is just emulating the roots... ;-)
DP> It`s "good enough" emulation :) You won`t notice much difference from
DP> the software side.
If you say so... ;-)
Cheers, Michiel
