Correct.
And in more words to help get rid of the mud...
They are called "channels" on vmails, not "ports" which are on the KSU.
1 Channel on vmail uses one channel on KSU.
1 KSU port has an A and B channel.

People mistakenly call it a "4 port" mail but most of us know that they mean.
JTELL posted 4 dots (....) which means 4 channels.
4 A's means Available, you can activate them with a key code.
Stars mean you need hardware upgrade, an MS-PEC card installed to allow for 8 more channels then you can key code those too.

"but if you have 4 cords coming into it, that would be an 8 port."
So the correct term is 8 Channel
