Dear All,

I am trying to setup the PSTN Router as per the configuration that I have 
received from IP Expert, however I need some clarifications as below. If any of 
you could help in this regard it would be great.

Why are these Translations Rules required on the PSTN Routers?
voice translation-rule 1
 rule 1 /^911$/ /\0/ type any unknown plan any unknown
 rule 2 /^\(2123942123\)$/ /\1/ type any subscriber plan any isdn
 rule 3 /^6178632683$/ /\0/ type any national plan any isdn
 rule 4 /^32141891$/ /34\0/ type any international plan any isdn
 rule 5 /^6745738932$/ /91\0/ type any international plan any isdn
 rule 6 /^9004522138$/ /\0/ type any national plan any isdn
!
voice translation-rule 2
 rule 1 /^911$/ /\0/ type any unknown plan any unknown
 rule 2 /^2123942123$/ /\0/ type any national plan any isdn
 rule 3 /^617\(8632683\)$/ /\1/ type any subscriber plan any isdn
 rule 4 /^32141891$/ /34\0/ type any international plan any isdn
 rule 5 /^6745738932$/ /91\0/ type any international plan any isdn
 rule 6 /^9004522138$/ /\0/ type any national plan any isdn
!
voice translation-rule 3
 rule 1 /^911$/ /999/ type any unknown plan any unknown
 rule 2 /^2123942123$/ /1\0/ type any international plan any isdn
 rule 3 /^6178632683$/ /1\0/ type any international plan any isdn
 rule 4 /^32141891$/ /\0/ type any national plan any isdn
 rule 5 /^6745738932$/ /91\0/ type any international plan any isdn
 rule 6 /^9004522138$/ /1\0/ type any international plan any isdn
!

Why are you translating to a number 1234, what is number 1234 here ?
voice translation-rule 34
 rule 1 /^011/ /1234/
 rule 2 /^911$/ /1234/
 rule 3 /^1617/ /1234/
 rule 4 /^1212/ /1234/
 rule 5 /^212/ /1234/
 rule 6 /^394/ /1234/
 rule 7 /^617/ /1234/
 rule 8 /^863/ /1234/
!
voice translation-rule 212
 rule 1 /^1212/ /1234/
 rule 2 /^1/ /\0/
 rule 3 /^394/ /\0/
 rule 4 /^011/ /\0/
 rule 5 /^212/ /\0/
 rule 6 /^911$/ /\0/
 rule 9 /./ /1234/
!
voice translation-rule 617
 rule 1 /^1617/ /1234/
 rule 2 /^1/ /\0/
 rule 3 /^863/ /\0/
 rule 4 /^011/ /\0/
 rule 5 /^617/ /\0/
 rule 6 /^911$/ /\0/
 rule 9 /./ /1234/
!

Why do you have to do this, is there any other way of doing this? You are 
saying that it is block call into BR1 but the Translation Rule does not have 
the reject command.
!
voice translation-profile block-call-into-BR1
 translate called 617
!
voice translation-profile block-call-into-BR2
 translate called 34
!
voice translation-profile block-call-into-HQ
 translate called 212
!
voice translation-profile display-proper-ani-into-BR1
 translate calling 2
!
voice translation-profile display-proper-ani-into-BR2
 translate calling 3
!
voice translation-profile display-proper-ani-into-HQ
 translate calling 1
