CCME SCCP

• Max-dn is default to 0.
  • Do not set this number higher than what's required as it consumes memory
  • This number also restricts the ephone-dn tag that can be configured e.g. Max-dn of 30 will not allow ephone-dn 31 to be created.
  • If you don't want all the ephone-dn to register with the gatekeeper by default, configure “[no-reg both]” globally to turn it off globally. May need to reboot the router for changes to take effect.
• Max-ephones is default to 0.
  • Again do not set this number higher than what's required as it consumes memory
  • It only limits the maximum number of ephone that can be registered
  • It does not limit the number of ephone that can be configured
• Specify the IP Port - port is default to 2000
• Create phone configuration files

telephony-service
  max-dn <number> [no reg both]
  max-ephones <number>
  !
  ip source-address <ip> [port <port-num>]
  !
  create cnf-files

• Enable by default

telephony-service
  auto-reg-ephone

• To show all auto registration attempt

Router# show ephone attempted-registration

• To auto assign DN
• All DN must be of the same type either single or dual-line but not mix
• The type if not specified will catch all
• cfw provide the Call Forward Busy Number and timeout value
• The DN needs to be defined as well

telephony-service
  auto assign <start-dn-tag> to <end-dn-tag> [type phone-type] [cfw <number> timeout <seconds>]
!  
ephone-dn <start-dn-tag> dual-line
  number 1000
...
ephone-dn <end-dn-tag> dual-line
  number 1999

• Default is 30s
• If three successive keepalive are missed, the device must register again

telephony-service
  keepalive <seconds>

• Specify the language to be displayed

telephony-service
  user-locale <language-code>

• Specify the call progress tones and cadence

telephony-service
  network-locale <language-code>

• Debug/Verify locales that is to be utilized by these devices

Router# show telephony-service tftp-bindings

telephony-service
  date-format {mm-dd-yy | dd-mm-yy | yy-dd-mm | yy-mm-dd}
  time-format {12 | 24}

• Use a loopback interface to bind H.323

interface loopback 0
  ip address <lo-ip> <mask>
  h323-gateway voip interface
  h323-gateway voip bind srcaddr <lo-ip>

• Provides detail information sorted and filtered using the options

CCME# show telephony-service [options]

• To see that the active ephone configuration
