[cisco-voip] CUCM 8.1.3 > Blocking inbound calls

Tue May 12 15:26:59 EDT 2015

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
