Hi,

I am building a Jtapi based application that needs to drop a call at some point, and I am doing like this:

Address address = provider.getAddress(extensionNumber);

			CallControlCall call = (CallControlCall) address.getConnections()[0].getCall();

			call.drop();

The call is dropped successfully, but I can see a Jtapi exception in the log files:
com.avaya.jtapi.tsapi.TsapiPlatformException: CSTA Error: 17

Does anyone knows why this exception is being thrown?

I am using jtapi version: '5.2.0.540 [production build]'
The AES version is 6.3

thanks,
Renato

Looks like the Jtapi client tried to remove a Call Monitor which did not exist. It may be that the monitor had already stopped automatically when the call ended.

I suggest that you change to using a newer version of the JTAPI SDK/Client.
