CISCO CUCM External Caller ID blocked

[RobertoGritar]

Hi everyone!
I need to block an external number (coming from PSTN) only in a specific telephone (if is posible)I mean, If I call from PSTN (e.g. 018180409409) to a specific extensión in my Call Manager (e.g. extension 1051) then I want that the display of my Ip Phone shows "private" or something, in order to the user does not know who is calling. And I refer only in a specific PSTN number and specific extension.

Regards!

The only way I know to do this is on your gateway router using a voice translation-rule in conjunction with a voice translation-profile that you then apply to the incoming pots dial peer(s). Also on the dial-peer set the answer-address to match the target callerID you wish to block (or redirect to the bit bucket).

I believe this topic was covered in the CVOICE training course and examples are shown in the course workbooks.

Could you tell me this topic name if you remember? In order to find the way cuz your explanation make sense but its a little bit complicated to apply.

Regards and thanks!

I apologize that I do not recall the exact topic. The procedure was explained on the white board and discussed in a CVOICE course I attended from Global Knowledge and led by an instructor named B.K. Jones.

Do a Google search for Translation Rules and you may find it. If I can get remote access to my Gateway routers I could do a cut-n-paste of the relative config areas. Let me try to explore that avenue and possibly post something that may help.

OK, here is the applicable portions of the Gateway router config:

!
voice translation-rule 5
 rule 1 /1234/ /*1234/
 rule 2 /6565/ /*6565/
 rule 3 /5650/ /*5650/
!
!
voice translation-profile NuisanceCallsToUnityRule5
 translate called 5
!
!
dial-peer voice 5000 pots
 description Force Nuisance Caller direct into Unity Cxn
 translation-profile incoming NuisanceCallsToUnityRule5
 answer-address 2814564000
 direct-inward-dial
!

In the above example we are saying that all calls from 2814564000 that are destined for extensions 1234, 6565, and 5650 will be blocked and redirected to the specific extension's voice mail (accomplished by prepending * ahead of their number as shown in Translation-rule 5

We then create a translation profile and reference it to translation-rule 5 with the 'translate called 5' statement

Finally we create a specific dial peer just for these calls. The 'answer-address' statement is the incoming callerID of the offending caller.

Therefore, all calls from 2814564000 that are destined for extensions 1234, 6565 and/or 5650 will not ring those extensions but will instead be immediately sent to their respective voice mailboxes.

Depending on the version of IOS running on your GW router you can have up to 100 entries in this voice translation-rule. I believe that capability requires IOS 15.3(t) or later. With earlier IOS the max size of the translation-rule is limited to 15 entries.

Good luck.
Hope this helps
