Re: IVR service - telephone exchange

Is this an analog system?  Some countries use cpe signalling, and some 
use tones to indicate end of call.  In Italy, I am guessing the latter. 
  Yes, it is possible the internal pbx and the telco use different 
tones, and the card is only set to recognize one of them...that could be 
very frustrating :).  What kind of/who's pbx/key system do you have on 
premise?  Maybe it has an option to change it's tone so you can set it 
to match the telco?  There might be other ways to do this, also.  For 
example, many key systems generate a call record on a serial (or 
parallel port) at the end of the call...in fact, I have wanted to do a 
web accessible call accounting system anyway for awhile, basically with 
a little daemon that parses the switch record and fills a sql table.
