The gateway is well firewalled to only allow connections from our SIP provider so I’m happy to allow anonymous calls but I can’t figure out how to tell the CUBE software (or is it CUCM?) to do this.<br>

CUCM is 8.6.2, the gateway is running IOS 15.1(4)M3<br>

Below is some example "debug ccsip calls"<br>
