Need to block the particular incoming number in SIP

[rajeshpat]

Hi All,

I got a request from my client that he wants to block a particular number (anonymous number) which he is getting call frequenting to his cisco IP phone. We have an H323 gateway and the gateway connected with ISP through SIP trunk. I have tried by creating translation pattern in CUCM and also tried configuring in gateway through the command "call-block disconnect-cause incoming" which is not working. So please help me how to do this. We have CUCM 11.5 and gateway was H323 and the ISP connection is SIP trunk.

Regards,

Rajesh

Depending upon what IOS you have on the router, you can apply an incoming sip profile to modify anonymous to an XXXX number. You can then block calls coming into CUCM with this ANI through a TP -
