[cisco-voip] CUCM 8.1.3 > Blocking inbound calls

[Ryan Huff]

You can try this technique http://ryanthomashuff.com/2014/11/call-blocking-by-caller-id/ which uses the "route next hop by calling party number". Works well for ANI call blocking; I'm using it to keep spam numbers off of uccx call center triggers. You have to apply it at the top of the dial plan though.

The Blocking Calls based on Calling Party Number has issues with CTI Redirects (UCCX/CER/Attendant Console) in that they won’t work on transfers to agent/phone/operator. 
 If you don’t use any CTI apps you would be good.
 
In IOS you can do a translation rule to reject but it’s limited to 100 rules.

If you're using H.323 or SIP for the voice gateway, easiest to block inbound via translation-profile on the incoming dial-peer.

 


If you have a lot of numbers you want to block or are using MGCP, you can do it in CUCM- https://supportforums.cisco.com/document/71966/blocking-calls-based-calling-party-id?page=1

Evening all,
 
I have had a request to block a specific number from being able to dial into our cluster, but have nothing currently setup to accomplish this.
 
The gateway is a Cisco C2921 running SPA.154-2.T.bin
 
Is it achievable to block the call on the gateway, or configure this somehow on CUCM.
 
Any assistance appreciated.
 
Regards
 
James
