Permitting only a specific country code for SIP calls

[Patrick.Williams]

I recently installed a VOIP router in Haiti, the carrier only supports sending calls with local ANI, if international is ANI passed you are billed at standard international rates coming into the island, I would like to know if there is a way I can create a translation rule to say if I see +509 XXX XXXX ani for a call pass, but for any other area code drop, send something like a 404 or something.

Please, check this article

You can combine tranlsation rule with call barring.
Something similar to this:

voice translation-rule 1
rule 1 reject /^[0-4]/
rule 2 reject /^[6-9]/
rule 3 reject /^5[1-9]/
rule 3 reject /^50[0-8]/

!-- explanation
!-- rule 1 reject /^[0-4]/ block any number with 0,1,2,3,4 at the start
!-- rule 2 reject /^[6-9]/ block any number with 6,7,8,9 at the start
!-- rule 3 reject /^5[1-9]/ block any number with 51,52,53 ... 59 at the start
!-- rule 3 reject /^50[0-8]/ block any number with 500,501,502 ... 508 at the start

!-- adjust the number format according to your situation

voice translation-profile BLOCKALL_EXCEPT_509_PREFIX
translate calling 1

and finally you must apply the translation rule to your dial peer, something similar to this:

dial-peer voice xx voip
call-block translation-profile incoming BLOCKALL_EXCEPT_509_PREFIX
call-block disconnect-cause incoming unassigned-number

Thank you for your response, I tried this config on my Router however it doesn't seem to be blocking any CLID, can you advise where I am going wrong. The rule is applied to the Pots Port associated with the provider PRI

voice translation-rule 100
rule 1 reject /^[0-4]/
rule 2 reject /^[6-9]/
rule 3 reject /^5[1-9]/
rule 3 reject /^50[0-8]/
rule 6 reject /^87[7-9]/
!

voice translation-profile BLOCKALL_EXCEPT_509_PREFIX
translate calling 100

dial-peer voice 2 pots
