/**
 * PBX API — main entry point.
 *
 * Supports three PBX back-ends (set PBX_DRIVER in .env):
 *   asterisk  — modern Asterisk 13+ with PJSIP / chan_sip (default)
 *   issabel   — Issabel PBX (community successor to Elastix)
 *   freepbx   — FreePBX (most widely deployed Asterisk GUI)
 *
 * See .env.example for all available configuration keys.
