Correct, its in the sequence you told the carrier you want.

Caveat, You _can_ have contention with analog lines. Meaning someone
calling in at precisely the same time as someone calling out - not
often, but it will happen. To help aleviate this, get the carrier to
roll the lines 1-2-3 and outbound you pick the lines 3-2-1.
