To anyone who is still following this thread, HOW ARE YOU GETTING YOUR CALLS "OFF" OF THE PSTN AND "INTO" YOUR CUCM ENVIRONMENT? I haven't seen this addressed by anyone; I'm attempting to bring my calls "in" from the PSTN through an FXO port on my cisco 2921 router with the following configuration on the FXO port: voice-port 0/1/0 connection plar opx 5088 caller-id enable type 1 Here is the configuration on my internal dial-peer that's pointing to my call manager: dial-peer voice 3 voip destination-pattern [2-9]...$ session target ipv4:172.16.3.160 dtmf-relay h245-alphanumeric rtp-nte On my CUCM, I'm using the "Gateway" option under the "Devices" menu. After following the above article, no matter what I do, my calls "are not" being blocked, to include my even trying to block the calls directly on the voice gateway. How are the rest of you configured so as to be able to block calls? Jay ... View more

@randall66: Randall, I still am not able to get this working; which "partitions" and "calling search spaces" are your phones and route patterns using once you are finished with the above configuration DKeller made available to everyone? I "think" that's part of the confusion some of us are experiencing... After all the above information is presented, it "IS NOT" clarified whether "EXISTING PARTITIONS/CALLING SEARCH SPACES" used by the internal numbers need to be changed to the new partitions in order for call blocking to work. Can someone clarify this please? Thanks... Jay ... View more
