[Freeswitch-users] freeswitch as fax/voice router

hi all, i am looking to use freeswitch to do uc fax/voice routing for my user did's. my users are on an ip pbx already (sipx, but the pre-freeswitch version, at least for now). i have calls coming into a pri and i'd like to use freeswitch to do fax detection on the call and do either fax-to-email or send the call to sipx. is anyone doing anything like this? is it feasible? clues for how to get started? thanks milosz
