Strange behaviour of my application

Q. I developed a console based application to monitor some terminals/addresses where I can see events happening on devices and send commands to devices.

Currently strange behavior is shown by my application. My application is unable to show events after 6-7 calls. But I am still pass commands through my application like makecall, holdcall or endcall.

I have added observers to Provider, terminal and address.

A. After 6-7 calls means is it like when calls made between two monitored phones. If that is the case i would request you to refer this url - StartRecording fails if calls made between monitored (2 agent's) phone for related information.  Let us know when exactly the issue occur like when you redirect the 6th call or something like that.
