Being more than a bit familiar with the use of conference calls in both contested and non-contested legal matters, I lean more to Schmedlap's position.

With respect to legal matters, they work best where everyone already has a written frame of reference - the relevant documents and briefs. And, of course, someone has to moderate the conference and enforce basic ground rules (which in a contested proceeding are spelled out for us).
