Hi
The dissector for the ActivityParameter of the ACTIVITY-START SPDU is using the
BER-Integer dissector while the activity parameter is in no case a BER encoded
integer (it could be a string or whatever decided by the SSAP peer)
>From packet-ses.c, line 665
case Activity_Identifier:
if (param_len == 0)
break;
if (tree)
{
dissect_ber_integer(FALSE, &asn1_ctx, param_tree, tvb,
offset,
hf_activity_identifier, NULL);
}
break;
Cheers
zos
