    • CUCME as SRST (Survivable Remote Site Telephony)
    • None (disables all Unified comms on the CME rtr
  9. If a IP phone not yet configures in CME contacts TFTP router, what file is sent?
  10. What is required in CME (minimal) to prepare rtr to accept IP phone registrations?

    • max-dn 60

    Note:  IP add and numbers are for example.
  11. what type of phone is created with the cmd ephone-dn 2?
    Single line
  12. What is the simplest way for an ephone-dn to  respond to both an internal extension and a call from outside (10 digit number - 4805551001)?

    • ephone-dn 12
    • button 3:5
  14. What show command us used to verify line assignment and registration status of IP phones?
    show ephone

    4. IP phones contacts TFTP server and gets config file and firmware

    5. Based on config file, IP phone registers with call processing server (subscriber server 1,2,3 then start again). 

    Small deployments have CME being the call processing server.
