Yes, you need a device which can simultaneously listen to the paging/controll channels and determine, when a handoff to a monitored conversation occurs,to which new channel pair they have been assigned. I seem to recall such a device was for sale a few years back using a ISA/EISA card and some DOS compatible software. It connected to the ubiquitous and well characterized Oki 900 cell phone.
I've also heard that some have hacked cellphones so that they can become a 'clone' of an existing phone, receiving all commands to swap channels, etc. But not sending anything back to the cell sites. (This is different from the usual cloning that goes on where they duplicate the phone and use it to run up enormous bills). I haven't found any concrete refrences to this in my recent browsing though, so it may just be a vapor-hack. Brian ---- www.eskimo.com/~nexus Nexus Computing ftp.eskimo.com/~nexus
