Also, please note that there is a limit of 15 rules in a translation-rule set. This method is only applicable to SIP and H.323 configurations. Translation rule 99 defines several patterns that should be rejected. Here we have dial-peer 99 handling inbound calls from the PSTN and it is configured to check the call setup and match it against the configured translation-profile. In older versions of Cisco IP Telephony Systems, call-blocking based on ANI was typically accomplished by using Translation-Profiles on Cisco IOS Voice Gateways, or ISR’s or CUBE (Cisco Unified Border Element).Ĭall-block translation-profile incoming blacklistĬall-block disconnect-cause incoming call-reject This blog focuses on all of the needed steps, and specifically the extra steps required when configuring this when using SIP as your primary gateway protocol versus MGCP or H323. We’ve seen many blog postings covering the steps to do this, however you have to read many different ones to properly implement and understand this configuration end-to-end, and more specifically, how to implement this when you are using SIP for your interior gateway protocol. Another scenario is maybe the caller is malicious, or keeps prank calling, so you may choose to simply reject the call, or send it to a specific pre-recorded message.Ī client may also want to block marketing calls, recruitment calls, or any other call that is generally unwanted. For example, if the Caller-ID or ANI (Automatic Number Identification) is that of a specific customer, then they may want to direct that call from that customer’s home number to a dedicated support representative, IVR, or Voice Message System. You have blocked all inbound calls originated from Australian Mobile numbers now.Some clients will request that their IP telephony system have the capability to block inbound calls into their organization, or to route these calls to a specific destination, solely based on the “Caller-ID” being sent by the caller. Goto “ Device=> Trunk” click on the SIP trunk, in Trunk Configuration page find Call Routing Information, in Inbound Calls change the Caling Search Space to CSS_Gateways. if you are using SIP you need to change it in Trunk configuration. The first translation patterns is changing the incoming calls Calling Search Space, also telling the CUCM to route the calls base on their ANI, on the second pattern we allowing the calls to go ahead with the routing to ward the CSS_Base which contains the internal directory numbers.ħ- Apply pattern here to block the unwanted calls for example, to block all incoming calls from 04XX XXX XXX numbers , you can do it by creating a Translation Pattern like belowĨ- The very last step is to set Calling Search Space for the Voice Gateways to CSS_Gateways for inbound call based on Calling party ID. please make sure you should create partitions that not included any internal number.Ĥ- Go to “ Call Routing => Class of Control => Calling Search Space” and click on Add Newĥ- Create CSS_Gateways, add PAR_Inbound_Calls to it, create CCS_Filter_List Calling Search Space and add PAR_Filter_List from available partitions.Ħ- Go to “ Call Routing => Translation Pattern” and click Add New, we need to create two translation patterns which are applied to all incoming calls by using the wildcard ! here are the process:ġ- Login to Cisco Unified CM AdministrationĢ- Go to “ Call Routing => Class of Control => Partition” and click on Add Newģ- Create two new Partitions PAR_Inbound_Calls and PAR_Filter_List. Sometimes it is needed to block some incoming calls for various reasons, it has been got so easy since Cisco introduced routing call based calling party number (AKA ANI and CallerID) in CUCM version 8 and newer.
