Syed,
 
Could you be more specific about what you want events you want to monitor, or ignore?
 
There are various "Filter" objects in JTAPI that allow you to essentially "ignore" JTAPI events and not receive them, but they do not cover all of the events. That is to say, some events cannot be ignored currently.
 
Let us know exactly what sort of events you want to blacklist or whitelist, and we can help you more.

Sanoop,
 
You can take a look at the CiscoTermEvFilter to limit the number of Terminal Events received. You can use the set methods to turn off events you're not at all interested in. There is a "bare minimum" that JTAPI sends, events which cannot be filtered out, which might be slightly more than you want, but you can reduce network traffic by using the filter and turning off what you don't need.
 
Currently, there is no filter for Call Events at the JTAPI layer.
