Thanks Matt,
  That worked like a charm. I simply commented out

#TDMV_DCHAN     = 16
in /etc/wanpipe/wanpipe1.conf

Now, whenever I try to place an outgoing call, using the outcall
spool. I'm receiving a hangup signal back from the switch. Here is the
debug output:

I'm not certain if I'm actually talking to the switch correctly or
just making the call incorrectly.

Thanks again,
