Hi All, The company I work for currently has quite an extensive phone network which gets carried between old analogue PABXes which also has an interface to IP based phones. All the phones in our office are connected via CAT5 cable using IP, however literally hundreds of phones out in the field (we operate railway infrastructure) are on standard voice analogue phones carried through fibreoptics. Anyway, I would like to use Freeswitch purely for its IVR and TTS abilities and nothing else. So basically I just need it to act like a slave to whatever IP phone network is already out there. I'm a bit worried if I fire up freeswitch it will hijack the phone network! All our phones are accessible via a 5 digit extension. I would like Freeswitch to be behind one of those ... say 12345. If anyone within our phone network dials 12345 then Freeswitch should answer. I guess my question is...how should I go about disabling most of FreeSwitch except it's ability to pick up the phone and speak IVR/TTS and make an outgoing call via the existing phone network? Any general pointers appreciated. Thanks, Oliver Schenk
