CLID is actually passed as HEX, therefore it can contain anything. I'd try to capture the DCH of the carrier inbound setup in MON 2 mode and look at the HEX:
Code:
HEADER:01 64 00 55 08 02 00 84 05
BCAP:04 03 80 90 A2
CHID:18 04 E9 A0 83 04
FAC :1C 11 11 FA A1 0D 02 01 01 02 02 01 00 CC
04 00 00 98 4D
PROG:1E 02 81 83
DISP:28 10 B1 4D 69 63 68 61 65 6C 20 57 69 6E
73 74 6F 6E
NLS5:9D
IPNW:40 0A 01 00 01 00 01 00 00 00 00 00
CLNG:6C 06 69 80 36 31 30 30
CLED:70 05 E9 34 30 30 33 This is a CDP call so the CLID is only 4 digits in red (6100 in this case), but you get the idea.
The '06' in Green is the number of HEX bytes to follow for that information element. It would be interesting if this is correct, or if you have a DCH message parsing error.
