There is a problem of decoding for the digitsResponse in the CAMEL
PromptAndCollectUserInformation return result.
The same message is correctly decoded as INAP (INAP and CAMEL are sometimes
very similar).
As a test, I did replace the hf_camel_promptAndCollectUserInformation with a -1
in packet-camel.c, and this seems to solve the current problem.
<<
static int dissect_returnResultData(proto_tree *tree, tvbuff_t *tvb, int
offset,asn1_ctx_t *actx) {
proto_item *cause;
switch(opcode){
case opcode_promptAndCollectUserInformation: /*
promptAndCollectUserInformation */
offset= dissect_camel_ReceivedInformationArg(FALSE, tvb, offset,
actx, tree, hf_camel_promptAndCollectUserInformation ==> -1 );
break;
>>
Of course, this is not the right file to correct.
But since the last changes in the dissector generation for ASN1 files, I am not
sure how to correct properly this bug.
I suppose there is something to change in camel.cnf ? Or maybe, there is a bad
check for the hf_ field ??
