Leaving a PBX without inventing a cutover

• Asterisk's article calls it a software PBX, created in 1999 by Mark Spencer, with voicemail, conferencing, IVR, and automatic call distribution.
• The Asterisk dialplan page says the dialplan is extensions.conf, typically in /etc/asterisk, and that dialplan reload loads it without disrupting service.
• DID and SIP trunking are how the outside world reaches that PBX, on the articles already opened.
• A CPaaS trunk can sit in the public domain while the PBX stays in the private domain.
• No cutover calendar, no dual-run week count, and no CUCM menu were opened.
