Hi Jonathan,
I include the same debugs with the calling and called party numbers:
*May 10 11:32:02.582: ISDN Se0/0/0:15 Q931: RX <- SETUP pd = 8 callref =
0x007F
Sending Complete
Bearer Capability i = 0x9090A3
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA18384
Preferred, Channel 4
Progress Ind i = 0x8183 - Origination address is non-ISDN
Calling Party Number i = 0x0083, '244560496'
Plan:Unknown, Type:Unknown
Called Party Number i = 0x81, '3300'
Plan:ISDN, Type:Unknown
*May 10 11:32:02.602: ISDN Se0/0/0:15 Q931: TX -> CALL_PROC pd = 8 callref
= 0x807F
Channel ID i = 0xA98384
Exclusive, Channel 4
*May 10 11:32:02.602: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref
= 0x807F
Cause i = 0x80A2 - No circuit/channel available
*May 10 11:32:02.790: ISDN Se0/0/0:15 Q931: RX <- RELEASE pd = 8 callref =
0x007F
*May 10 11:32:02.802: ISDN Se0/0/0:15 Q931: TX -> RELEASE_COMP pd = 8
callref = 0x807F
*May 10 11:33:35.062: ISDN Se0/0/0:15 Q931: RX <- SETUP pd = 8 callref =
0x0057
Sending Complete
Bearer Capability i = 0x9090A3
Standard = CCITT
Transfer Capability = 3.1kHz Audio
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA18383
Preferred, Channel 3
Progress Ind i = 0x8283 - Origination address is non-ISDN
Calling Party Number i = 0x0083, '244502150'
Plan:Unknown, Type:Unknown
Called Party Number i = 0x81, '3300'
Plan:ISDN, Type:Unknown
*May 10 11:33:35.086: ISDN Se0/0/0:15 Q931: TX -> CALL_PROC pd = 8 callref
= 0x8057
Channel ID i = 0xA98383
Exclusive, Channel 3
*May 10 11:33:35.086: ISDN Se0/0/0:15 Q931: TX -> DISCONNECT pd = 8 callref
= 0x8057
Cause i = 0x80A2 - No circuit/channel available
The '3300' number is associated with two translation patterns. One points to
a Hunt Pilot (5930) that is associated to a partition (WorkHours) which is
further associated to a Time Schedule containing several Time Periods. The
other one points directly to a DN (5250) associated to a different partition
(NonWorkHours) further associated with a Time Schedule that contains several
Time Periods.
