Is there any reason why the dissection for ISUP Generic notification hasn't
been implemented? The cause codes are actually present (as comments) in the
packet-isup.c.
Currently the message "Refer Q.763 for detailed documentation" is being

Attached are some traces for the case.
The following changes in packet-isup.c is correcting the dissection:
