Send Random Phone Number Mask

[matthubach]

Would anyone happen to know how to send random phone number masks on outbound calls?

We own 6 different DID's from our telco. We have changed their Caller ID Name to "unkn". I'd like to somehow randomly assign one of these 6 numbers to outbound calls.

They're routing out SIP T's. I originally thought I could do this via CCM, but I can't find a way. Now I am thinking dial-peers. There are only a few phones that will have the ability to do this. It's law enforcement related.

Thoughts?

No native way to do what you're asking, and it's impossible in CUCM, your only option would be to develop a TCL script to do that and do the ANI change in the GW.

It's possible with CUCM using CURRI (https://developer.cisco.com/site/curri/overview/).

Thank you both! Never worked with TCL scripting before...I'll take a look at it.

Jaime is correct no native way in CUCM to do that. You can try to use the translation-rules on the gateway. Some thing similar to below:

1) Crate translation rules and map DID mask:

voice translation-rule 1
 rule 1 // /12345/               <<< DID 1
voice translation-rule 2
 rule 1 // /56789/              <<< DID 2
voice translation-rule 3
 rule 1 // /0123/                  <<< DID 3

2) Create Translation-profiles, translating the calling number to above DIDs

voice translation-profile CLID-1
 translate calling 1
voice translation-profile CLID-2
 translate calling 2
voice translation-profile CLID-3
 translate calling 3

3) Apply to dial-peers:

dial-peer voice 1 voip
 translation-profile outgoing CLID-1
dial-peer voice 2 voip
 translation-profile outgoing CLID-2
dial-peer voice 3 voip
 translation-profile outgoing CLID-3

The dial-peers should have same destination-pattern and (same preference which is default) should be picked up randomly.

Thanks for the insightful way Terry (+5), and just adding to Terry's point.

If your Outgoing dial-peers are exactly same, you can make it Random Selection by the following command:

dial-peer hunt 6  (6 = random selection) by default it is 0 (longest match)
