[asterisk-ss7] Errors on a SS7-Link with libss7

[Matt Fredrickson]

It just means that you received a message that the ISUP of libss7 doesn't do anything with.  It looks like it's a CFN message.  Also looks like you recieved a few optional parameters that are ignored by libss7 too.  The optional parameters shouldn't cause a problem.  I'll have to see what CFN is used for.
