   Use the show telephony-service all or the show running-config command to verify that SRST fallback mode has been set on this router.

   Example:
   telephony-service
   srst mode auto-provision all
   srst ephone template 5
   srst ephone description srst fallback auto-provision phone : Jul 07 2005 17:45:08
   srst dn template 8
   srst dn line-mode dual
   load 7960-7940 P00305000600
   max-ephones 30
   max-dn 60 preference 0
   ip source-address 10.1.68.78 port 2000
   max-redirect 20
   system message “SRST Mode: Cisco Unified CME’
   keepalive 10
   max-conferences 8 gain -6

   Step 2
   Use the show telephony-service ephone-dn command during fallback to review ephone-dn configurations. Learned ephone-dns are noted by a line stating that they were learned during SRST fallback.

   Example:
   ephone-dn 1 dual-line
   number 4008
   name 4008
   description 4008
   preference 0 secondary 9
   huntstop
   no huntstop channel
   call-waiting beep
   ephone-dn-template 8
   This DN is learned from srst fallback ephones

   1. Rick, on this same page is the example of this question, and the answer is;
      ephone-dn 1 dual-line
      number 7001
      description 7001
      name 7001
      ephone-dn-template 5
      This DN is learned from srst fallback ephones
