IVR service - telephone exchange

Hi, 

I have made an IVR service bayonne-dialogic based. This service runs in a 
company that has a telephone exchange that connects phone calls. 

If I call the IVR service with an inner telephone, the hangup event is not 
recognized. But if I call the IVR service from an external telephone, the 
hangup event is recognized. 

Which problem can the system has? Hangup frequency? 

Thanks!!
