[Freeswitch-users] CISCO 2811 - FreeSwitch - IVR

Hey all,


I have successfully managed the following setup ... at least to a
certain extent.


Phone line -> CISCO VIC2-4FXO -> CISCO 2811 -> Sip -> Windows Server
2008 -> FreeSwitch -> Managed IVR (IAppPlugin)


When I dial say the phone line's number (49794) it connects me to
extension 1024 which has the managed C#.NET IVR sitting behind it. That
works fine while everything is happy. However, when I hang up my phone.
My IVR is still happily talking to no one until the relevant timeouts
expire. Is this the normal way to implement it? Just wait for timeout?
Or do I have some CISCO configuration issues?


Shouldn't the CISCO tell FreeSwitch that "Hey ... the guy on the line
has put down his phone receiver so you can end your session now."?



Any comments?
