Finally confirmed problem - wanted to update issue : (I am not sure if this might be relative to other carriers, but definitely for Sprint and specifically the "Airvana 2nd generation")

1. Call waiting tones (the beep you hear when on an active call) when someone else calls are transmitted/generated from your carrier's network end.

2. I was not receiving this at home. I was also connected to an airvana unit. It is sprint's network antenna booster. They have 2 generations of this device - one made by samsung (which only handled voice) - the second called "airvana - which handles voice and 3g data)

1st generation airave when activating MAC - allowed network tones to be transmitted.

2nd generation did not work in that regards. Reason : Found out sprint has a list of phones that have known issues to this 2nd generation, and HTC TP2 is one of them.

When out of the airvana network, the TP2 Sprint edition worked
.
When on the 1st generation airave (samsung) - TP2 call waiting works.

When on the 2nd generation airvana (TP2 call waiting ***does NOT work)


Hope this clarifies -

If you have a device and have noticed this lack of call waiting, contact airvana support at : +1-866-556-7310 (United States) to see if your device is on the list.
