Hi all, I'm dissecting Camel packet by using wireshark. I see most of my packet are "Camel-v1" or "Camel-v2" or "Camel" and nothing else. So:

  1. Does this mean my camel packets are version 1, version 2 ?
  2. How can I know the version of Camel packet if it is unknown (Protocol = "Camel" on GUI)?
  3. I check the code (branch trunk-1.10) and don't see other versions (Camel-v3, Camel-v4...) in the code. Does this mean this code of Wireshark does not support Camel version 3 and version 4?
  4. If the answer of question 3 is YES (IT DOESN'T SUPPORT): I read a book "Intelligent Network for the GSM, GPRS and UMTS Network" and it says:

One of the enhancements to the O-BCSM and the T-BCSM, compared with CAMEL phase 3,is the introduction of the alerting detection points. The following DPs are used for the alerting event: O-BCSM: O Term Seized; and T-BCSM: T Call Accepted

As I understand, if so, only camel-v4 has "O Term Seized" and "T Call Accepted" but I search in the wireshark code (which support only version 1 and version 2), there are values for "O Term Seized" and "T Call Accepted" as below:

static const value_string camel_EventTypeBCSM_vals[] = {
  {   2, "collectedInfo" },
  {   3, "analyzedInformation" },
  {   4, "routeSelectFailure" },
  {   5, "oCalledPartyBusy" },
  {   6, "oNoAnswer" },
  {   7, "oAnswer" },
  {   8, "oMidCall" },
  {   9, "oDisconnect" },
  {  10, "oAbandon" },
  {  12, "termAttemptAuthorized" },
  {  13, "tBusy" },
  {  14, "tNoAnswer" },
  {  15, "tAnswer" },
  {  16, "tMidCall" },
  {  17, "tDisconnect" },
  {  18, "tAbandon" },
  {  19, "oTermSeized" },
  {  27, "callAccepted" },
  {  50, "oChangeOfPosition" },
  {  51, "tChangeOfPosition" },
  {  52, "oServiceChange" },
  {  53, "tServiceChange" },

My question 4 is: If wireshark 1-10 does not support v3, v4, so why there are code string for values of v4 only? And if wireshark 1-10 support v3, v4, so why I cannot find out the indication of these versions in the code?

Thanks for your help :)
