Have you spoken with your carrier to see what they accept for national numbers?  Most providers are ok with Unknown / Unknown, but others are not.   What do you have your Called party IE number type unknown and Called Numbering Plan set to?

Anyone seen this issue before?  I have a couple MGCP voice gateways, and am getting reports that certain numbers are returning fast busys (some long distance, some 888 numbers).  If I do a q931 debug I see the following output.

What is meant by "Temporary Failure"?  I can call the number fine from my cell phone and from the legacy PBX system, which uses the same carrier that's used on our MGCP gateways.
