Thanks! I also find the CLID matching to be an irritant. It is easy in most cases to bypass but screws up your CLID when you do so. What other methods are you seeing carriers using to verify validity?

Use SIP Profiles on your router to change anonymous@ to XXXXXXXXXX@

Your carrier should rethink how they are receiving SIP Invites and what credentials are being used to verify the validity of the invite message. I know that doesn't solve your problem, but it's incredibly irritating to see how some carriers are (mis)handling SIP trunks.

Is there any way on the CUBE or Call Manager to change the anonymous to a ten digit number? I also have the Rightfax team looking into changing this on the Rightfax side but I like to have options
