[cisco-voip] CCM - CLIR?

[Lelio Fulgenzi]

I'll admit, it can get complicated, but as far as I know, it's the only way to preserve the calling restrictions put in place on the system. Since there is no way to force a translation pattern to take on the calling search space of the originating caller, you need to use seperate translations, each one reflecting the calling search space of the original calling party. If you know of a better (or easier) way, please let me know.

Let's take this example: 

Partitions: Group_A_PT, Group_B_PT, Group_C_PT
CSS       : CSS_A={Group_A_PT, Group_C_PT} and CSS_B={Group_B_PT}

Directory No: 5001 in Group_A_PT w/ CSS_A
Directory No: 5002 in Group_B_PT w/ CSS_B
Directory No: 5003 in Group_C_PT w/ CSS_B

If I want to restrict calling ID presentation for both 5001 and 5002, they have to be able to dial a translation pattern which resets this. For example, 5XXX w/ calling party presentation restricted. The transformed digits are left empty.

If I create just one translation pattern that all phones use, then the translation pattern calling search space must include Group_C_PT so that 5001 can call 5003. By doing so, if 5002 dials 5003, the call goes through. I need to prevent 5002 from dialing 5003.

In order to do that:
  a.. I create two new calling search spaces, CSS_A_FromPriv={FromPriv_A_PT} and CSS_B_FromPriv={FromPriv_B_PT}. 
  b.. I create two translations:
    a..  5XXX w/ restricted party presentation and CSS of CSS_A in FromPriv_A_PT
    b..  5XXX w/ restricted party presentation and CSS of CSS_B in FromPriv_B_PT
  c.. I assign 5001 CSS_A_FromPriv and assign 5002 CSS_B_FromPriv
Now, calls from 5001 and 5002 appear as 'From Private' and calling restriction is preserved - 5001 can call 5003 and 5002 can not.

I'm hoping 4.1 implements calling restriction in a better way.

  Hi Lelio,

  If you use a translation pattern with special prefix, I do not 
  understand why this requeires additional calling search spaces?
