I have created a Dial-peer for the Cisco UC500 or CME. A client had asked me how to disable Caller-ID on their Cisco UC540 phone system on a per call basis (not all the time and only for some calls). The issue was using UC540 with a PRI in PBX mode.. the user must dial a 9 to get an outside line. Verizon was requiring the user to dial a *67 to disable or block Caller ID to the called party. Dialing a *67 into the Cisco phone system would give the user a fast busy tone.. because it does not have a dial peer that can handle the *67 digits. so my solutions was to add a dial-peer that allowed the user to dial an 8 to get an outside line for any calls he would like to block his caller ID to the outside world. This way normal calls will use the 9 and when blocking his caller ID is required he can use the 8 to dial an outside line.
I created dial-peer 99 (which was free on the system) which looks for the user to DIAL 8+PHONE NUMBER to disable Caller-ID. This dial-peer calls a translation profile that modifies the number sent to verizon.

rule 1 /^8/ /*67\1/
***This rule says “Strip the Digit 8 and then add and send *67(plus the rest of the number) to verizon.
As you can see if I run the UC540 through a test…. The number I DIAL is 82038741273 and it translates it to *672038741273 and now will send the caller-id blocking code to the ISP.
