CLASS 1.6 (Protocol error; e.g. unknown message)Cause No. 96 –
Mandatory Info missingThis cause indicates that the equipment sending
this cause has received amessage which is missing an information
element which must be present in themessage before that message can be
processed.
This is your first clue. Don't mess with the part that works. Start
by trying different values on span 3 (or is it 2? you call it both).
I would try switchtype=national first. I would also try things like
localdialplan=unknown pridialplan=unknown and other signalling related
settings and flip the possible settings around until it works. Look
at the example files on your box for ideas.
I bet you will have a "holy cow! It worked" moment and nobody will
have to spoon feed you the answer.
Thanks,
Steve Totaro
