do you know if its possible to interface the analog telephony card
using the 9 pin connector to the mic-in jack of a motorola talkabouts
so that you have an inexpensive 'base station  receiver and transmitter'
and can you then control the sub-channels that a call is made on to the 
2-way radios so you can address each 2-way talkabout indivdually ?
