The IETF is not the standards body controlling the SI numbers...
However, I'll update the mtp3 dissector to make use of the higher
values. Please note that the MTP3 dissector uses additional SI values
(taken form an ITU recommendation):
static const value_string mtp3_service_indicator_code_vals[] = {
{ 0x0, "Signalling Network Management Message (SNM)" },
{ 0x1, "Maintenance Regular Message (MTN)" },
{ 0x2, "Maintenance Special Message (MTNS)" },
{ 0x3, "SCCP" },
{ 0x4, "TUP" },
{ 0x5, "ISUP" },
{ 0x6, "DUP (call and circuit related messages)" },
{ 0x7, "DUP (facility registration and cancellation message)"
},
{ 0x8, "MTP testing user part" },
{ 0x9, "Broadband ISUP" },
{ 0xa, "Satellite ISUP" },
{ 0xb, "Spare" },
{ 0xc, "Spare" },
{ 0xd, "Spare" },
{ 0xe, "Spare" },
{ 0xf, "Spare" },
{ 0, NULL }
};
Best regards

Hi,
RFC3332 lists the SI:s as:
Service Indicator. Depending on the MTP3 protocol variant/version
used in the network appearance, additional values may be used.
The relevant MTP3 protocol variant/version recommendation is
definitive.
0 to 2 Reserved
3 SCCP
4 TUP
5 ISUP
6 to 8 Reserved
9 Broadband ISUP
10 Satellite ISUP
11 Reserved
12 AAL type 2 Signalling
13 Bearer Independent Call Control (BICC)
14 Gateway Control Protocol
15 Reserved
At a glance I haven't found it specified in ITU doc's above 10 but
perhaps we should use this values until proven wrong and update
packet-mtp3.c accordingly?
Actually in 1.1901 it says:
NOTE 1 ? The value of the Service Indicator for the Bearer Independent
Call Control is "13" (see
ITU-T Q.704 [12] and ITU-T Q.2210 [13] and its respective
Implementors' Guides).

In Q.704 SI 14 is declared as Spare.
H.248.5 (in ch. 4) states:
Protocol messages defined in this Recommendation may be transmitted
over an SS7 network.
Service indicator value 14, [...]
So, I'll say it's officially registered.

I've allways seen that one, although only on ericsson machinery.
