Lab 1

Posted: July 2, 2006 by cciestudy in Cats
  1. interface vlan — give no shut
  2. line vty >> exec-timeout 0 0 
  3. check in phones if DHCP is enabled
  4. give ip helper-address. If you enter it wrong, take it out using no command before entering the new one, because it does not overwrite
  5. IPPhone auto registration. Auto registration was enabled in pub, but in the Callmanager group, pub was listed second. Hence phones did not register. Always use Pub for auto registration and list Pub first. After the phones register, disable autoregistration and rearrange the callmanager group.
  6. Autoregistration, use dummy phone range so that you will not run into shared line issues later. Turn off auto registration after the phones get registered
  7. Did not configure IOS DHCP along with DHCP Server
  8. ATA was not DHCP enabled
  9. enter isdn switch-type before moving to controller mode
  10. linecode and framing defaults are sf and ami, need to change this
  11. Use codec preference in dial-peers so that calls  from the gateway to phones at the same site can use g711 and calls to remote sites can use g729
  12. Check CAC, codec and SRST section and add regions and locations and then create the device pool and add all these to the phones and gateways at the same time. Remember to set Call forward on lines to VM
  13. Add external phone number mask to phones
  14. Did not configure  voice class for h323 dial-peer redundancy
  15. Did not apply CSS to phones
  16. When making changes to phones, do not reset them individually. Make changes to all phones and then reset them all at the same time.
  17. Check Urgent Priority for 911 and 9911
  18. Shared lines does not sync external phone number mask. Check the Update Shared device settings
  19. Forgot to add pots dial-peers on BR2 gateway.
  20. Forgot to add TEHO partiton to BR2-Ph2.
  21. Enable dependency records in Enterprise parameters. Change all DNS names to IP Address
  22. AAR does not need any additional partitions or CSS. You can apply the least restrictive CSS to the AAR CSS as well as either the Long distance or international partitions depending on the scenario.
  23. Do all calling party and called party transformations at Route list
  24. Forgot to add Prefix digits to HQ route group in BR2-local route list
  25. TEHO Route pattern should have been 90111212.[2-9]XXXXXX, added it as 90111212.XXXXXXX
  26. If Telco is sending 10 digits, set the Significant digits in gateway to 4 (to match internal extension length) or create individual translation patterns to convert 10 digits to 4 digits.
  27. Forgot to enable Display IE delivery on H323 gateway
  28. Forgot to enable default application in H323 gateway for MGCP fallback
  29. Forgot mgcp dtmf-relay voip codec all mode out-of-band
  30. Forgot to add voice  port to service mgcp dial-peer
  31. Forgot to add dual-line in max-dn srst
  32. Forgot voice rtp send-recv
  33. set port auxiliary vlan should be used on phone ports
  34. set route pattern from branch 2 to site 1 teho as long distance. But it should have been setup as international call.
  35. do not need direct inward dial on all dial peers, use this with incoming called number in one dial-peer
  36. voice class h225 timeout was set to 10 change this to 3
  37. forward digits set it to 7 for 7 digit local dialing
  38. on h323 gateways add dial peer for 911 separately. otherwise calls will fail if predot is set at route pattern level.
  39. set caling party extph mask setting on route list. as number of route lists will be less. number of route patterns will be too many so checking ext phone number mask at each route pattern will take more time.
  40. always put prefix digits in route list in called party
  41. forgot to check enable status poll on mgcp gateways (fractional)…
  42. didnt set aarcsss in gateways (br2 and 6608)
  43. set h323 gateway route patterns to discard digits NONE if gateway dail-peers are 9T
  44. set h323 gateway with dial-peers (individual dial peers) or .T as the destination pattern if using discard digits Predot at route pattern
  45. forgot 9911 in srst gateway
  46. used 2 extra dial peers for 4 digit dialing. instead can use num-exp
  47. used num-exp to map incoing calls (10 digit to 4 digits). dialplan pattern is enough…
  48. when calls come from pstn on a h323 gateway and it needs to send call to a local phone, the call needs to be g711. if it goes to a phone in another region, then that will need a g729 codec. use voice class codec to achieve this.

voice class codec 1

codec pref 1 g711ulaw

codec pref 2 g729r8

dial-peer voice 1 voip

destination-pattern 1…

voice-class codec 1

    – It can be wrong. Did you have FTP and CCM services enabled on subscriber?

    Hmmm why would you do that… why not just set your groups (SUB/PUB) and turn auto-reg on the sub?? Why all the hoops?
