Yeah, a person redirect traffic to another IXC (long distance carrier) by
overriding the CIC.  For example, 1010925+1+TheNumber to put a call on YAK,
or 1010363 to put it on Bell Canada.  The problem I have is that I didn't
think someone else can sneak calls into my PRI.. it's not like its analog
and they can jam a call onto the line by simply splicing into the copper?!?

That's about right.  Generally speaking, you only send through a PIC
request on a line when something changes with the service.. like it moves
or gets disconnected/reconnected for some reason.

Thanks for the tip.  I'm going to look into that.
