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

[Wilusz, Mike]

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.

 

 

DC-VOICE-GW-2#

Jul  9 13:42:53.964: ISDN Se0/0/0:23 Q931: TX -> SETUP pd = 8  callref =
0x0092

        Bearer Capability i = 0x8090A2

                Standard = CCITT

                Transfer Capability = Speech

                Transfer Mode = Circuit

                Transfer Rate = 64 kbit/s

        Channel ID i = 0xA98397

                Exclusive, Channel 23

        Calling Party Number i = 0x0081, '518355XXXX'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '18882449615'

                Plan:Unknown, Type:Unknown

Jul  9 13:42:54.416: ISDN Se0/0/0:23 Q931: RX <- CALL_PROC pd = 8

        Channel ID i = 0xA98397

                Exclusive, Channel 23

Jul  9 13:42:54.768: ISDN Se0/0/0:23 Q931: RX <- PROGRESS pd = 8
callref = 0x8092

        Cause i = 0x8AA9 - Temporary failure

        Progress Ind i = 0x8488 - In-band info or appropriate now
available

Jul  9 13:42:56.580: ISDN Se0/0/0:23 Q931: TX -> DISCONNECT pd = 8
callref = 0x0092

        Cause i = 0x8190 - Normal call clearing

Jul  9 13:42:56.596: ISDN Se0/0/0:23 Q931: RX <- RELEASE pd = 8  callref
= 0x8092

Jul  9 13:42:56.616: ISDN Se0/0/0:23 Q931: TX -> RELEASE_COMP pd = 8
callref = 0x0092

DC-VOICE-GW-2#

 

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.
