Accessing net thru Bluetooth,stil inc.calls r busy

[meetashwin_16]

hi,
I have a very strange experience & wanna share with u guys for more discussion & expert comments.
I have SE W550i,Airtel GPRS. to access net.I generally uses bluetooth to access net.All u guys know that when using using bluetooth,u can answer incoming calls(in case of cable, phone enters into data transfer so we r not able to answer,as callers r getting engage tone).Ok enough.
But I am getting busy tone still on bluetooth not everytime but only when i starts Bearshare File sharing prog.It is a P2P soft.
But I am just curious what it is causing the phone to be busy ?
If every1 getting same experience with same case ?
Post some expert comments
