CUBE - Using voice translation rules to block specific numbers

[AEledge]

Hello!

We are currently using a voice translation rule to reject calls from specific numbers at the CUBE level (see attached screenshot), but we have reached the maximum (100) and I haven't been able to stack multiple voice translation rules on the incoming dial-peer. My question is, would it be possible to use a text file stored in bootflash to accomplish this, and would it remove the maximum of 100 for this use case?

Example of what I'm thinking:

voice translation-rule 2

url bootflash:/blocked-numbers.txt

If this were to work, would the text file even need to contain the rule numbers, or could it just be a number on each line in e164 format?

Thanks again

AFAIK this is not possible. Only translations can be made by loading a file. For more information see this document. Explain Cisco IOS and IOS XE Call Routing

Could you maybe use an e164-pattern-map with a "incoming calling e164-pattern-map XXX" included in the dial-peer and blackhole the dial-peer? The e164-pattern-map would give you up to 1000 entries in the config and up to 5000 in a referenced file. 

I haven't pondered how that would interwork with your incoming called-number style dial-peer so it might not work, but if you google "IOS XE" and "Multiple Pattern Support on a Voice Dial Peer" you should find reference material.

Hi -

You didn't say whether you have CUCM or not. But if you do you might want to look at blocking calls in that system. Take a look at this post for an overview of that process.
