Steve,

	I take it you have one D channel for all four spans?  On 24?  I think 
this should be pretty transparent to wanpipe.  You should configure four 
spans, with one channel group (type TDM) per span (obvious).  You should 
also probably disable any "native D channel" features.  I always have 
nothing but problems with that.  In zaptel.conf, only specify one d 
channel.  The "tricky" stuff is in zapata.conf.  Can you post that, and 
maybe zaptel.conf too?
