Advanced Dial Plans

Modifying caller-id (ANI) information

Reasons to change caller-id

• Display four-digit extensions internally
• Display full number externally
• adding and removing “9” on external calls

Commands to change caller-id

• station-id (name/number) - voice port
• clid network-number - dial peer
• clid strip name - dial peer
• clid restrict - dial peer

Translation Rules

• Allow you to change called (DNIS) or calling (ANI) information
• similar to calling/called transformation in CUCM
• Uses regular expressions to transform
• Translation rules are created, places in profile, profile assigned
• Rules in the format of /match/ then /change/
• sub-rules can be created per rule

Rule Examples

!! Replace extension 4000 with 6500
rule 1 /^4000$/ /6500/

!! carry extension over - shortcut
rule 2 /^7...$/ /1800555&/

!! carry extension over - set zero
rule 3 /^7...$/ /1800555\0/

!! \( \) creates a set
!! add area code
!! match 9555.... carry over set 1 add 480 then carry over set 2
rule 4 /\(9\)\(555....\)/ /\1480\2/

!!Match anything
rule 5 /.*/ /1000/

!!Match anything except blank
rule 6 /.+/ /1000/

!! change extensions 7xxx to 8xxx
rule 7 /^7\(...\)$/ /8\1/

Extension to DID on failover configuration

voice translation-rule 1

	port 1/0/0
	translation-profile outgoing PSTN_FAILOVER

Class of Restriction

• Requires more detailed dial-peers (no 9T for PSTN)
• Restrictions implemented via COR list
• Incoming dial-peer assigns incoming COR list
• Outgoing dial-peer assigns outgoing COR list
• If the outgoing COR list is a subset of the incoming COR, the call is forwarded
• If user does not have a COR list assigned, they can dial anything (no restrictions)

1. Define COR custom tags

dial-peer cor custom
  name 911call
  name localcall
  name ldcall
  name internatcall

2. Define outgoing COR lists

dial-peer cor list EMERGENCY
  member 911call

dial-peer cor list LOCAL
  member localcall

dial-peer cor list LONGDIS
  member ldcall

dial-peer cor list INTERNAT
  member internatcall

3. Define incoming COR lists (assigns permissions to users)

dial-peer cor list LD
  member 911call
  member localcall
  member ldcall

4. Typical North America PSTN Dial plan with COR lists assigned

dial-peer voice 911 pots
  description EMERGENCY_CALLING
  destination-pattern 911
  no digit-strip
  corlist outgoing EMERGENCY
	
dial-peer voice 9911 pots
  description EMERGENCY_CALLING
  destination-pattern 9911
  forward-digits 3
  corlist outgoing EMERGENCY
	
dial-peer voice 10 pots
  description 10-DIGIT-DIALLING-LOCAL
  destination-pattern 9[2-9].........
  corlist outgoing LOCAL
	
dial-peer voice 11 pots
  description 11-DIGIT-DIALLING-LONG-DISTANCE
  destination-pattern 91[2-9].........
  prefix 1
  corlist outgoing LONGDIS
	
dial-peer voice 12 pots
  description INTERNATIONAL
  destination-pattern 9011T
  prefix 011
  corlist outgoing INTERNAT

5. COR list assigned to a user

dial-peer voice 5000 pots
  destination-pattern 5000
  port 1/0/1
  corlist incoming
