I will guess at what Dave (MooreTel) was saying.

For Sales press 1, Service press 2, Accounting press 3

Then in path 1 say:
For Joe press 1, John press 2, Sally press 3.

Then in path 2 say:
For Mary press 1, Henry press 2.

Then in path 3 say:
For Susan press 1, Mary Beth press 2.

Hope you can figure it out from there.
