<p class=MsoNormal>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.<span style='font-family:"Courier New"'><o:p></o:p></span></p>

<p class=MsoNormal>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. <o:p></o:p></p>
