[cisco-voip] Certain Outbound Numbers - ISDN "Temporary Failure"

[Mike Hawley (AU)]

What do you have on the voice interface for "Bearer Cap"?  I have seen in the past a requirement to turn off "Bearer Cap" completely - "no bearer cap"

All the best

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.
