Spec 11 §6.2: a phone's directory is the extensions, its owner's own contacts (accepted shares included), then the company's, in both modes. In Contrack mode, contacts from before Contrack are offered for copying (contrack.toCopy, POST …/copy-to-contrack: one Contrack bulk import, skipping what's already there; the builtin rows stay). Tested against a fake and a real Contrack 2.0.2.
