[cisco-voip] Facility IE cnam delivery and SIP

Ahh, It looks like I only saw the Status in your debug.  Looking further down at your facility message, I think this is the issue.  5ESS switches shouldn't be using Facility for calling name- https://supportforums.cisco.com/thread/2038757

Brian,

     I'm reading that as us sending that towards the carrier switch, if I set as national it will not transmit that message upon receiving the facility IE, it instead breaks it out and processes it. I'm reading that this is as per 5ESS specifications, caller name shouldn't be sent in a facility message, so it's not something that IOS would process when treating it as a 5E, thus the error. If that's really the case I suppose I don't expect it to be a real bug and repairable, but I am no ISDN pro - that's for sure.
