A google for "DAHDI pcap" led me to the following page: http://forums.digium.com/viewtopic.php?f=1&t=82833 That suggests that DAHDI 2.6 onwards can be compiled with pcap support, that presumably provides the drivers with the ability to capture to pcap files, and a tool to control it. Presumably a recent version of Wiresharl will then be able to interpret the captured files.
