being a definitive "right" way. All are correct.
Some people will use the full acronym,
pronouncing each letter "V-O-I-P".
Some people will use the first two words
combined with IP (pronounced as separate letters).
This is actually more like a phrase "Voice-Over-I-
P".
Some will say the acronym as a word, just as it
sounds (like void only with a p at the end) "voyp".
