Of course - and that is just fine.  If you were running ethernet 
signalling over that CAT5 than your 100m limit would apply.  If you were 
running gigabit over that same cable its more like 80 feet.  He isn't 
asking about ethernet signalling.  As many posts have shown this morning, 
the actual length limit for running analog voice and DTMF signalling over 
the cable depends on many things that the OP probably has no control over.
YMMV, like most things.
