Works great! I use this to trigger changing my GTalk status to busy with a custom message of "on the phone".
Got for tasker($6.49 compared to locale's $10), which accepts incoming call as a trigger, but not active call.
Great! This is exactly what I need. I badly wanted to disable vibrate for new emails during calls.
Doesn't turn off Usually, when going from "In Progress" call to "Default", my status doesn't change
Works well. Thanks!
