I've been asked to allow Anonymous calls in CUCM across a SIP trunk from the PSTN. I don't have the option checked to reject Anonymous calls on the DN, however calls are still getting dropped. Looking through the logs in CUCM I'm getting a 404, but if i redial the same number and remove the *67 on the call it completes fine. Do i need to change the Validate Refer-to URI to Never Validate for this to work?
