Yes, you can use a T100P and have * act as the network side of a PRI (using 
pri_net) and talk to an existing PBX.

zaptel.conf need to have your T100P span set up correctly (I'd use the PBX as 
the clock source as it's probably got a more stable clock than anything in 
the computer) with channels 1-23 as bchan and 24 as your dchan.  In 
zapata.conf you set up pri_net signalling and put all channels 1-23 in a 
group and give them some default context you want your PBX to dump in to.  Do 
not give an entry for channel 24 at all.
