Multi-jump communications would create unacceptable delay in a voice

That's why trans-Atlantic/Pacific cables remain popular.

Cables are popular because they're *cheaper* than satellites
(per unit of delivered bandwidth) what with the incredible advances
in fiber optics.

Has anybody ever heard of Echo-Cancelling devices? These can mitigate the
effect of the "bounce" to a great degree. Also, to compensate further,
"Reverb" can be added to flesh out tone and timbre.

Echo cancelling does nothing to reduce time-of-flight issues.
A half-second delay is still a half-second delay.

Adding reverb is contraindicated for telephone communications,
as it tends to reduce intelligibility. Check out speakerphones
for examples thereof. As a matter of fact, there is a fair bit
of research for _reducing_ reverberation in speakerphones.

Signal processing techniques are not useful for fixing problems
due to speed of light causing delays.

300,000 km/second: not just a good idea, it's the law.
