[cisco-voip] ISDN PRI: Service/Option not available, unspecified

[Dave Wolgast]

When we try 800 toll-free numbers from a new customer site in Puerto Rico,
we get the following (Calling and Called party numbers masked by me):

001378: May 16 15:26:41.878: ISDN Se0/1/0:23 Q931: Applying typeplan for
sw-type 0xD is 0x2 0x1, Calling num 787XXXXXXX
001379: May 16 15:26:41.882: ISDN Se0/1/0:23 Q931: Sending SETUP  callref =
0x00B0 callID = 0x8031 switch = primary-ni interface = User
001380: May 16 15:26:41.882: ISDN Se0/1/0:23 Q931: TX -> SETUP pd = 8
 callref = 0x00B0
        Bearer Capability i = 0x8090A2
                Standard = CCITT
                Transfer Capability = Speech
                Transfer Mode = Circuit
                Transfer Rate = 64 kbit/s
        Channel ID i = 0xA98383
                Exclusive, Channel 3
        Calling Party Number i = 0x2181, '787XXXXXXX'
                Plan:ISDN, Type:National
        Called Party Number i = 0x80, '1800XXXXXXX'
                Plan:Unknown, Type:Unknown
001381: May 16 15:26:41.946: ISDN Se0/1/0:23 Q931: RX <- CALL_PROC pd = 8
 callref = 0x80B0
        Channel ID i = 0xA98383
                Exclusive, Channel 3
001382: May 16 15:26:43.054: ISDN Se0/1/0:23 Q931: RX <- PROGRESS pd = 8
 callref = 0x80B0
        Cause i = 0x82BF - Service/option not available, unspecified
        Progress Ind i = 0x8488 - In-band info or appropriate now available
001383: May 16 15:26:46.742: ISDN Se0/1/0:23 Q931: TX -> DISCONNECT pd = 8
 callref = 0x00B0
        Cause i = 0x8090 - Normal call clearing
001384: May 16 15:26:46.778: ISDN Se0/1/0:23 Q931: RX <- RELEASE pd = 8
 callref = 0x80B0
001385: May 16 15:26:46.782: ISDN Se0/1/0:23 Q931: TX -> RELEASE_COMP pd =
8  callref = 0x00B0

It seems to happen with any 800 number we send, but does not seem to be
happening with 877 or 866 numbers. The toll free numbers chosen seem to be
accessible from other landlines in Puerto Rico.

Any advice is appreciated.
